<h3>What are hydrocarbons?</h3>

Hydrocarbons are any of a group of organic compounds that exclusively contain the elements carbon (C) and hydrogen (H) (H). The structural framework of the molecule is formed by a number of interactions between the hydrogen and carbon atoms.

<h3>What is hydrocarbon made of?</h3>

Hydrocarbons, which are only composed of carbon and hydrogen, make up the majority of crude oil, refined petroleum hydrocarbons (including gasoline, diesel, kerosene, fuel oil, and lubricating oil), coal tar, creosote, dyestuff, and pyrolysis waste products.

Two 0.75 Amp loads are connected in parallel with a 2500 Milliamperehour Ni-Cd battery. Approximately how long can the battery p

nikdorinn [45]

Explanation:

It is given that two loads have 0.75 Ampere current each. And, they contain 2500 milli ampere per hour Ni-Cd battery.

As both the loads are connected in parallel. Hence, total current will be calculated as follows.

I = $I_{1} + I_{2}$

= 0.75 A + 0.75 A

= 1.5 A

= $1.5 A \times \frac{1000 mA}{1 A}$

= 1500 mA

Relation between time and capacity of battery is as follows.

Capacity = Current × time (in hour)

therefore, time = $\frac{Capacity}{Current}$

= $\frac{2500 mA. h}{1500 A}$

= 1.667 hr

Thus, we can conclude that the battery provide power to the load up to 1.667 hours.

Answer the following questions based on the reaction below: NaOH(aq) + KHP(s) --> NaKP(aq)+H2O(I)

Natali [406]

Answer:

<u />

<u>a) 1.44g</u>

<u />

<u>b) 77.3%</u>

<u />

Explanation:

<u>1. Chemical balanced equation (given)</u>

$NaOH(aq)+ KHP(s)\rightarrow NaKP(aq)+H_2O(l)$

<u>2. Mole ratio</u>

$1molNaOH(aq):1molKHP(s)$

This is, 1 mol of NaOH will reacts with 1 mol of KHP.

<u />

<u>3. Find the number of moles in 72.14 mL of the base</u>

$Molarity=\text{number of moles of solute}/\text{volume of solution in liters}$

$\text{Volume of solution}=72.14mL=0.07214liters$

$\text{Number of moles of NaOH}=0.0978M\times 0.07214liter=0.007055mol$

<u>4. Find the number of grams of KHP that reacted</u>

The number of moles of KHP that reacted is equal to the number of moles of NaOH, 0.007055 mol

Convert moles to grams:

mass = number moles × molar mass = 0.007055mol × 204.23g/mol

mass = 1.4408 g.

You have to round to 3 significant figures: 1.44 g (because the molarity is given with 3 significant figures).

<u>5. Find the percentage of KHP in the sample</u>

The percentage is how much of the substance is in 100 parts of the sample.

The formula is:

% = (mass of substance / mass of sample) × 100

% = (1.4408g/ 1.864g) × 100 = 77.3%
