The HOTTEST and most efficient fuel GAS. The hottest and most efficient of all fuel gases, acetylene (C2H2) provides high levels of productivity thanks to good localised heating with a minimum of thermal waste. ... Acetylene is the only fuel gas recommended for underground WORKING conditions because it is LIGHTER than air.

The law of conservation of mass states that mass in an isolated system is neither created nor DESTROYED by CHEMICAL reactions or PHYSICAL transformations. ACCORDING to the law of conservation of mass, the mass of the products in a chemical REACTION must equal the mass of the reactants.

how does pressure affect the freezing point of WATER?Explanation:For most substances, the freezing point rises, though only very slightly, with INCREASED pressure. Water is one of the very rare substances that expands upon freezing (which is why ice floats). Consequently, its melting temperature FALLS very slightly if pressure is increased.plz MAKE as brainliest

yes that's true...EXPLANATION:carbon carbon dioxide under high pressure is forced into/ MIXED water or any other COMPOUND (solvent)...... this results in the FORMATION of of carbonic acid which is a a weak acid and gives sour taste......

The biggest advantage of DC electricity is that it is easier to store than AC electricity, especially on a small scale. Storing electricity when it is made, for use later when it is needed, is a critical CONCEPT for a hybrid INDEPENDENT power plant. When electricity is stored we can use it when we need it, and storing it increases its density, so we can take as much power as we want to OPERATE high-powered equipment. When we store electricity we can turn the generator set off most of the time which saves fuel, and we can use electricity when our renewable sources such as solar CELLS are not providing electricity. The best way to store electrical energy for relatively small-scale applications is to use rechargeable storage batteries. We can RETRIEVE electricity from a storage battery bank silently, efficiently, and immediately when we need it. Storage batteries require DC electricity, so to get the advantages of storing electricity in a storage battery bank, we must generate DC electricity.

The second ionization ENERGY of Mg is larger than the first because it always takes more energy to remove an electron from a POSITIVELY CHARGED ION than from a neutral atom. The third ionization energy of magnesium is enormous, however, because the Mg2+ ion has a filled-shell electron configuration.

0.056 is the SIGNIFICANT FIGURES

At any given TEMPERATURE, small, LIGHT molecules (such as H 2, hydrogen gas) DIFFUSE faster than larger, more massive molecules (such as N 2, nitrogen gas) because they are TRAVELING faster, on the average (see heat ; kinetic-molecular theory of gases ).

Answer : The MOLALITY of solution is, 0.8 mole/KgSolution : Given,Mass of solute, glucose = 36 gMass of solvent, water = 250 gMolar mass of glucose = 180 g/moleMolality : It is defined as the NUMBER of moles of solute present in the ONE kilogram of solvent.Formula used :Molality=\frac{w_b\times 1000}{M_b\times w_a}Molality= M B ×w a w b ×1000 where,w_bw b = mass of solute, glucosew_aw a = mass of solvent, waterM_bM b = molar mass of solute, glucoseNow put all the given values in the above formula, we getMolality=\frac{36g\times 1000}{180g/mole\times 250Kg}=0.8mole/KgMolality= 180g/mole×250Kg36g×1000 =0.8mole/KgTherefore, the molality of solution is, 0.8 mole/Kg

ohhh THATS a TOUGH question hmmmm LET me FIGURE it outExplanation:

ou need to start off by WRITING out a balanced chemical equation which will SHOW you the relationship between CaCO3 and CO2: CaCO3 + 2HCl → CaCl2 + CO2 + H2O This equation tells you that for every mol of CaCO3 consumed you will be producing 1 mol of CO2. In other words there is a 1:1 relationship between CaCO3 and CO2. The next step is to determine the AMOUNT of CaCO3 you have in moles, and since HCl is in excess, you do not need to worry about which one is the LIMITING r

e S Block Elements? The s block elements having only one electron in their s-orbital are called group one or alkali metals whereas the s block elements having two ELECTRONS FILLING their s-orbital are called group two or alkaline earth metals. The electrons present in an atom occupy various sub-orbitals of available energy levels in the order of increasing energy. The last electron of an atom may find itself in either of the s, p, d and f subshells. Accordingly, the elements of the atom having their last valence electron present in the s-suborbital are called the s block elements.What are F Block Elements? Elements whose f orbital getting filled up by electrons are called f block elements. These elements have electrons, (1 to 14) in the f orbital, (0 to 1) in the d orbital of the penultimate energy level and in the outermost’s orbital. There are two series in the f block corresponding to the filling up of 4f and 5f orbitals. The elements are 4f series of Ce to Lu and 5f series of Th to Lw. There are 14 elements filling up the ‘f’ orbital in each series.What are D Block Elements? Elements having electrons (1 to 10) present in the d-orbital of the penultimate energy level and in the outer most ‘s’ orbital (1-2) are d block elements. Although electrons do not fill up ‘d’ orbital in the group 12 metals, their chemistry is similar in many ways to that of the preceding groups, and so considered as d block elements. These elements typically display metallic qualities such as malleability and ductility, high values of electrical conductivity and thermal conductivity, and good tensile strength. There are four series in the d block corresponding to the filling up of 3d, 4d, 5d or 6d orbitals. 3d- Sc, Ti, V, Cr, Mn, Fe, CO, Ni, Cu, Zn 4d- Y, Zr, Nb, Mo, Tc, Ru, Rh, Pd, Ag, Cd 5d- La, Hf, Ta, W, Re, Os, Ir, Pt, Au, Hg 6d- incomplete. There are 10 elements filling up the ‘d’ orbital in each series.

The Michael ADDITION mechanism starts off with the deprotonation of the ,-unsaturated carbonyl compound by the BASE. This generates a carbanion, which finds stability due to its electron WITHDRAWING groups. The Michael reaction was first defined by Arthur Michael, an AMERICAN organic chemist.

The actinoids are radioactive elements having relatively SHORT half-lives. The elements of actinoid series COULD be prepared only in NANOGRAM quantities. This is the REASON why their study is more difficult.

Pour DISTILLED water—20 to 30 mL less than the final volume—into the BEAKER, then ADD sodium CARBONATE. In our example, start with 270 to 280 mL of water

The PRODUCT formed for ALDOL condensation is called β-hydroxy aldehyde or β-hydroxy KETONE.

In order for the reaction to be a full NEUTRALIZATION, TWICE as many moles of NaOH MUST react with the H2SO4. The sodium SULFATE salt is soluble, and so the net ionic reaction is again the same. Different mole ratios occur for other polyprotic acids or BASES with multiple hydroxides such as Ca(OH)2
