Filling in the gaps in the excerpt below

Molecules that do not  __Dissociate__________ (or come apart) in solution are called ___Non-electrolyte substances_________ . Most of these substances are covalently bonded __and do not conduct electricity__________ (e.g., glucose, urea, and creatinine). In contrast, a(n) ___Electrolyte_________ is any substance that dissociates in solution to form Salts

<h3>Difference between electrolytes and Non-electrolytes</h3>

Electrolytes are substances that conduct electricity because they readily ionize when placed in a solution. while Non-electrolytes do not readily conduct electricity because they do not dissociate  into ions when placed in a solution.

Hence we can conclude that the answers to your questions are as listed above.

An experiment was conducted with a 1.57 gram starting mass of copper. How many grams of cooper were collected if the yield was 8
IRINA_888 [86]

Answer:

1.26 g of Cu

Explanation:

Since we have to find the percentage of the given amount so...

Yield in grams = (Initial mass used / 100) x Percentage Yield

Yield in grams = (1.57 / 100) x 80.6 = 1.26 g of Cu

A 0.211 g sample of carbon dioxide, CO2, has a volume of 560 mL and a pressure of 429 mmHg whats the temperature of the gas in K
SCORPION-xisa [38]

The temperature of the gas sample is 813 K.

<u>Explanation:</u>

We have to use the ideal gas equation to find the temperature of the gas sample.

The ideal gas equation is PV = nRT

Pressure, P = 429 mm Hg = 0.56 atm

Volume, V = 560 mL = 0.56 L

R = gas constant = 0.08205 L atm mol⁻¹K⁻¹

Mass = 0.211 g

Molar mass of carbon di oxide = 44.01 g / mol

Moles, n = $\frac{given mass}{molar mass} = \frac{0.211 g}{44.01 g/mol}

              = 0.0047 mol

Now, we have to plugin the above values in the above equation, we will get the temperature as,

$T= \frac{PV}{nR}

T = $\frac{0.56  \times 0.56}{0.08205 \times 0.0047}

 = 813 K

So the temperature of the gas sample is 813 K.

What is the temperature change if 400 J of energy is added to 10 grams of water
Gemiola [76]

The temperature change if 400 J of energy is added to 10 grams of water is 9.57°C.

<h3>How to calculate temperature change?</h3>

The temperature change of a calorimeter can be calculated using the following expression:

E = mc∆T

Where;

  • E = energy in joules
  • m = mass
  • c = specific heat capacity = 4.18J/g°C
  • ∆T = change in temperature

400 = 10 × 4.18 × ∆T

400 = 41.8∆T

∆T = 400/41.8

∆T = 9.57°C

Therefore, the temperature change if 400 J of energy is added to 10 grams of water is 9.57°C.
