What would be the temperature change 3.0 g of water absorbed 15 J of heat

Chemistry
1 answer:
frosja888 [35]3 years ago
8 0

Answer:

1.2 °C  

Step-by-step explanation:

The formula relating the heat (q) absorbed by an object, the mass (m), and the temperature change (ΔT) is

  q = mCΔT     Divide both sides by mC  

ΔT = q/(mC)

<em>Data: </em>

q  = 15 J

m = 3.0 g

C  = 4.184 J·°C⁻¹g⁻¹

<em>Calculation: </em>

ΔT = 15/(3.0 × 4.184)

ΔT = 15/12.6

ΔT = 1.2 °C

What is the scaling factor if the molar mass of
Step2247 [10]

Answer:

The scaling factor is 5.

Explanation:

Hello there!

In this case, since the scaling factor is defined as the ratio of the molar mass of the molecular formula (complete) to the empirical formula (simplified), it is possible to compute it for the empirical formula of CH2O whose molar mass is 30 g/mol (12+2+16) as shown below:

sf=150/30=5

Therefore, we can also infer that the molecular formula would be:

C_5H_1_0O_5

highlight why it is important to evaluate important assessment studies before any development could be made on the environment​
Kay [80]

Answer:

Essentially, an EIA is designed to identify the potential risks of a project (e.g., infrastructure development such as a dam) to environmental and human well-being and identify measures to eliminate and/or mitigate these risks. This can be done by replacing and/or modifying planned activities to reduce impacts

PLEASE HELP!!!!!!
pogonyaev

Answer:

m_{B}^{theoretical}=0.365gB

Y=87.1\%

Explanation:

Hello there!

In this case, since the reaction (A->B) have an initial amount of pure 4-aminobenzoic acid, the first step to compute the theoretical yield is to solve the following stoichiometric setup:

m_{B}^{theoretical}=0.303gA*\frac{1molA}{137.14gA}*\frac{1molB}{1molA}*\frac{165.19 gB}{1molB}\\\\   m_{B}^{theoretical}=0.365gB

Whereas A stands for 4-aminobenzoic acid and B for the benzocaine. Moreover, we compute the percent yield by dividing the actual yield (0.318 g) by the theoretical one (0.365 g):

Y=\frac{0.318g}{0.365g} *100\%\\\\Y=87.1\%

Best regards!

Which of the following will increase solubility the rate of the dissolving process of a gaseous solute in solvent? (mark all tha
Pepsi [2]

Answer: The increase in solubility or the rate of dissolving process of a gaseous solute in a liquid solvent is due to following:

  • Increasing agitation
  • Increasing temperature
  • Increasing solute's partial pressure over the solvent
  • Increasing solute's surface area

Explanation:

When agitation is increased then there will occur an increase in kinetic energy of the molecules of a substance. As a result, more number of collisions will take place due to which more amount of solute will dissolve into the solvent.

Similarly, increasing the temperature will further increase the kinetic energy of molecules. Hence, this will lead to more solubility of gaseous solute into the liquid solvent.

As solubility of a gas is directly proportional to the pressure of the gas above surface of the solution. So, an increase in solute's partial pressure over solvent will also lead to an increase in solubility of gaseous solute into liquid solvent.

When surface area of solute is increased then there will be more solute particles available for reaction. Hence, more collisions will take place. As a result, rate of reaction is more due to which there will be an increase in solubility.

Thus, we can conclude that the increase in solubility or the rate of dissolving process of a gaseous solute in a liquid solvent is due to following:

  • Increasing agitation
  • Increasing temperature
  • Increasing solute's partial pressure over the solvent
  • Increasing solute's surface area
