Answer:

The reaction is the following:

MgCO3 + H2SO4————————→ MgSO4 + CO2 + H2O

You will see evolution of carbon dioxide. It is an exothermic reaction.

Explanation:

What happens when magnesium carbonate reacts with acid?

Like many common group 2 metal carbonates, magnesium carbonate reacts with aqueous acids to release carbon dioxide and water:

MgCO3 + 2 HCl → MgCl2 + CO2 + H2O.

What products are produced when magnesium carbonate reacts with sulfuric acid?

Reactions of acids with carbonates

• Acid + carbonate → salt + water + carbon dioxide.

For example:

• Hydrochloric acid + copper carbonate → copper chloride + water + carbon dioxide.

Other carbonates also react with dilute acids. For example:

• Sulfuric acid + magnesium carbonate → magnesium sulfate + water + carbon dioxide.

How many moles are in a 275g sample of K2CrO3

Marrrta [24]

Answer:

There are approximately 1.54 moles in a 275 g sample of $K_2CrO_3$ .

Explanation:

To find out number of moles, fistly we have to calculate molecular mass of $K_2CrO_3$ .

There are 2 atoms of Potassium 1 atom of Chromium and 3 atoms of oxygen in the given compound.

For molecular mass we have to add the value of mass of 2 atoms of Potassium with mass of 1 atom of Chromium and with mass of 3 atoms of oxygen.

Atomic mass of Potassium = 39

Atomic mass of Chromium = 52

Atomic mass of Oxygen = 16

Now,

Molecular mass of $K_2CrO_3$ = $2\times 39+52+3\times 16=78+52+48=178\ gm$

The molecular mass of a compound is the mass of compound in one mole.

To find out the number of moles, we have to divide given mass of compound by its molecular mass.

$Number\ of\ moles=\frac{given\ mass}{molecular\ mass}$

$Number\ of\ moles=\frac{275}{178}= 1.54$

Hence the number of moles in 275 gm of $K_2CrO_3$ is 1.54.

A sample of Neon is in a sealed container held under isothermic conditions. The initial pressure and volume are 2.7 atm and 4.5

Marina CMI [18]

Answer:

The final volume in mL is 7.14 mL or 7.1 mL.

Explanation:

1.Use Boyle's Law( $P_{1} V_{1}= P_{2} V_{2}$ ). Re-arrange to solve for $V_{2}$ for the final volume.

2. Plug in values. $V_{2} =\frac{(2.7 atm)(4.5 mL)}{(1.7 atm)} = 7.14 mL$

What is the density of an object if it has a mass of 73 grams and a volume of 3.8cm3?

SashulF [63]

The density of the object is 19 g/cm³.

The mass of the object is 73 g.

The volume of the object is 3.8 cm³.

Density = mass/volume = 73 g/3.8 cm³ = 19 g/cm³
