Give a chemical formula for the compound formed when sulfur dioxide reacts with water

zavuch27 [327]

When sulfur dioxide reacts with water , the product is called sulphurous acid, H2SO3. The balanced equation is expressed in the following manner : SO2 + H2O = H2SO3. There is a one mole to one mole ratio between any of the reactants to product, sulphurous acid.

In a coffee-cup calorimeter, 100.0 g of H2O and 100.0 mL of 1M HCl are mixed. The HCl had an initial temperature of 44.6 C and t

Hatshy [7]

Answer:

Exothermic reaction for the HCl, endothermic reaction for the water

$2803.28\ \text{J}$

Explanation:

Heat was lost by HCl as its temperature lowered, so it was an exothermic reaction for the HCL.

Heat was gained by water as its temperature increased, so it was an endothermic reaction for the water.

m = Mass of water = 100 g

c = Specific heat of water = $4184\ \text{J/kg}^{\circ}\text{C}$

$\Delta T$ = Change in temperature of water = $(31.3-24.6)^{\circ}\text{C}$

Heat is given by

$Q=mc\Delta T\\ =0.1\times 4184\times (31.3-24.6)\\ =2803.28\ \text{J}$

Heat gained by water is $2803.28\ \text{J}$ .

The atom in a sample of an element must contain nuclei with the same number of?

slava [35]

Hey there!

Answer: Protons

The atom in a sample of an element must contain nuclei with the same number of protons. If the protons change in number, then the element will modify as well.

Thank you!
