Explanation:

because 100+40=140

HIGH SPEED

EXPLANATION:

EQUAL to

Decantation

Decantation can be used to separate immiscible liquids that have DIFFERENT densities. For example, when a mixture of water and OIL is present in a beaker, a DISTINCT LAYER between the two consistency is formed, with the oil layer floating on top of the water layer.

Answer:

Answer:When ZINC is added to copper sulphate (CUSO4) solution due to more reactivity of zinc, cooper is replaced by the zinc and forms zinc sulphate. During the process, the colour of the solution changes from blue to colourless.The chemical equation of the REACTION,ZN + CuSO4 → ZnSO4 + CU

caco3=40% , CALCIUM = 12% , OXYGEN =48%

ong>Answer:

Hydrogen SULPHIDE will form

Explanation:

SIGHT - It will be colorless

Smell- It's smell is as a ROTTEN EGG..

Hope it helps....

Pls Mark me as brainliest if you found this really helpful.

ong>Answer:

At high temperatures or in the presence of catalysts, SULFUR dioxide reacts with hydrogen sulfide to FORM elemental sulfur and WATER. Hydrogen sulfide and its solutions are colorless. When EXPOSED to air, it SLOWLY oxidizes to form elemental sulfur, which is not soluble in water.

SO3, CH2O, COCl2

Explanation:

SO3 and BF3 both have trigonal planar structure hence they are isostructural.

CH2O and BF3 both have trigonal planar structure hence they are isostructural.

COCl2 and BF3 both have trigonal planar structure hence they are isostructural.

Please.. Put a 'Thanks' for it.. And MARK me and my answer as the brainliest..

ong>Answer:

We know

Mass of fuel× calorific value=mass of water ×specific HEAT ×temperature difference

Given mass of fuel m

F

=10 kg and mass of water m

= 2kg

ΔT=70

ong>Answer:

1. If the number of electrons in the outer shell is between one to four, the compound is said to have positive valency. For compounds with electrons four, five, six, or seven, the valency is determined by subtracting the electron from eight.

2.Certain elements combine with other atoms, donating, accepting or sharing electrons in DIFFERENT proportions depending on the NATURE of the reaction. For example, iron combines with oxygen to form ferrous oxide as well as FERRIC oxide. This is termed variable valency.
