How much heat is added if 0.0318g of water is increased in temperature by 0.364 degrees C?

SSSSS [86.1K]

Answer:

0.04838J

Explanation:

Heat is a form of energy that is transferred from one body to another as the result of a difference in temperature between the bodies , here heat is added to the water as a result of temperature change of 0.364 degreesC

Given:change in temperature=0.364

Mass of water=0.0318g

But we need specific heat capacity of water which is

4.2 J/g°C

Then we can calculate How much heat is added by using below formula

Energy = Mass * specific heat capacity *(change in temperature)

energy =0.0318g* 4.18g*0.364

=0.04838J

How many moles of CH4 are in 148.6 g? Round your answer to two decimal places.

Dafna1 [17]

Answer:

9.29 mol

Explanation:

Given data:

Number of moles = ?

Mass = 148.6 g

Solution:

Number of moles = mass/ molar mass

Molar mass of CH₄ = 16 g/mol

Now we will put the values in formula.

Number of moles = 148.6 g/ 16 g/mol

Number of moles = 9.29 mol

Thus 148.6 g have 9.29 moles.

Complete and balance the equations for the following double displacement reactions:

RideAnS [48]

Answer:

A. AgNO₃ + NaCl —> AgCl + NaNO₃

B. Mg(NO₃)₂ + 2KOH —> 2KNO₃ + Mg(OH)₂

C. 3LiOH + Fe(NO₃)₃ —> Fe(OH)₃ + 3LiNO₃

Explanation:

The equation given in the question above can be balanced as follow.

A. AgNO₃ + NaCl —> AgCl + NaNO₃

The above equation is already balanced.

B. Mg(NO₃)₂ + KOH —> KNO₃ + Mg(OH)₂

There are 2 atoms of H on the right side and 1 atom on the left side. It can be balance by writing 2 before KOH as shown below:

Mg(NO₃)₂ + 2KOH —> KNO₃ + Mg(OH)₂

There are 2 atoms of K on the left side and 1 atom on the right side. It can be balance by writing 2 before KNO₃ as shown below:

Mg(NO₃)₂ + 2KOH —> 2KNO₃ + Mg(OH)₂

Thus, the equation is balanced.

C. LiOH + Fe(NO₃)₃ —> Fe(OH)₃ + LiNO₃

There are 3 atoms of H on the right side and 1 atom on the left side. It can be balance by writing 3 before LiOH as shown below:

3LiOH + Fe(NO₃)₃ —> Fe(OH)₃ + LiNO₃

There are 3 atoms of Li on the left side and 1 atom on the right side. It can be balance by writing 3 before LiNO₃ as shown below:

3LiOH + Fe(NO₃)₃ —> Fe(OH)₃ + 3LiNO₃

Thus, the equation is balanced.
