nch of SCIENCE concerned with the substances of which matter is COMPOSED, the investigation of their PROPERTIES and reactions, and the USE of such reactions to form NEW substances.

Hydrogen is flammable, but OXYGEN is not. ... When hydrogen combines with oxygen the result is water, where the atoms of hydrogen and oxygen are linked together to MAKE a molecule with ENTIRELY different PROPERTIES. You can't burn pure water, which is why we use it to put out fires instead of starting them.

AlCl3Explanation:the 3RD GROUP has 3 electron in outermost shell while 7TH group has 7 electron in outermost shell....so AlCl3..

टार्टरिक एसिड एक कार्बनिक यौगिक है जिसका आणविक सूत्र COOH (CHOH) है2COOH। इसके दो कार्बोक्सिल समूह हैं; अर्थात्, यह दो प्रोटॉन (एच) जारी कर सकता है+)। दूसरे शब्दों में, यह एक द्विध्रुवीय अम्ल है। इसके अलावा, इसे एक एल्डरिक एसिड (अम्लीय चीनी) और एक succinic एसिड व्युत्पन्न के रूप में वर्गीकृत किया जा सकता है.

An expression containing variables, numbers, and OPERATION symbols is called an algebraic expression. is an example of an algebraic expression. Each expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable or variables.\huge\underline{\underline{Types :)}} Types:) There are three basic types of algebraic expressions. They are; Monomial-Which has only one non-zero term. Binomial-Which has TWO non-zero terms. Polynomial- Which has more than one non-zero terms with non-negative integral exponents.mark me as BRAINLIST

petroleum is USED as a source of energy, being rich in FUEL carbon in ELECTRICITY generation or RUNNING some kinds of heat engines. Raw petroleum (also known as crude oil) is used in THREE main ways: transport, generating electricity, and producing materials.

tify the acid and basic radicals in GIVEN salt mixture NOTE the smell and colour of salt. The salt colour should be white and there should be no smell.Heat a pinch of salt in a dry test tube. The colour of the salt will GET reddish brown.I HOPE YOU LIKE MY ANSWER AND I AM ASMITA SONAM BARLA. THANK YOU AND GOD BLESS YOU.

The leaves of certain plants exhibit droplets of WATER along their margins in the morning. This particularly happens in plants growing in warm humid conditions. A humid environment hampers transpiration while the roots continue to absorb water from the soil. This builds up a BIG hydrostatic pressure within the plant and “forces out” the excess water directly from the tips of veins in the leaf. SPECIAL pore-bearing structures called hydathodes are present on the margins of the leaf to allow this EXUDATION.

The usual oxidation state of boron and ALUMINUM is +3, WHEREAS the heavier ELEMENTS in group 13 have an INCREASING tendency to form COMPOUNDS in the +1 oxidation state.

Salts which are FORMED by the PARTIAL NEUTRALIZATION of a base by an acid are called BASIC Salt : )

lts are a class of salts that produce an acidic SOLUTION after being dissolved in a solvent. Its FORMATION as a substance has a greater electrical conductivity than that of the PURE solvent. An acidic solution formed by acid salt is MADE during partial neutralization of DIPROTIC or polyprotic acids.

The CONJUGATE acid of PO4(3-) is HPO4(2-).

A CHANGE which can happen BACKWARD, that is, can be REVERSED is called a reversible change. If you keep water in the freezer for some time, it transforms into ice. But as soon as you take it out of the freezer, it turns into water again. This is a reversible change.

andhmjffggegegehskykdykydkydmsymAnswer:EXPLANATION:

tion:Calculate the Kb for the base.PO4^3- + HOH ==> HPO4^2- + OH^-Kb for PO4^3- = (Kw/k3 for H3PO4) = 1E-14/4.2E-13 = about 0.024. Even though 0.024 is a "relatively" large number in Kb terms (and PO4^3- is a STRONG base in terms of pH), it is less than 1 which means the NUMERATOR is SMALL and the denominator is large. That means that the reactants predominate at equilibrium

ter (from ampere meter) is a measuring instrument USED to measure the CURRENT in a circuit. Electric currents are measured in amperes (A), hence the name. The ammeter is USUALLY connected in series with the circuit in which the current is to be measured. An ammeter usually has low resistance so that it does not cause a significant voltage DROP in the circuit being measured.if you want any help ASK ok.

Dalton's atomic theory was the first complete attempt to DESCRIBE all matter in TERMS of ATOMS and their properties. ... The first part of his theory states that all matter is made of atoms, which are indivisible. The second part of the theory says all atoms of a given ELEMENT are IDENTICAL in mass and properties.
