Answer:

Option A

Explanation:

Looking at the following formula:

I = V/R

Where V is voltage, I is current and R is resistance

In the above equation, Current and Voltage are in direct relationship such that if I is increased , V is also increased and vice versa. So, To increase the current, voltage should be increased.

Sunlight is more spread out as you move away from the equator.

suter [353]

Answer:

False.

Explanation:

<u>The given statement asserts a false claim because the equator is the region that receives maximum sunlight</u>. The equator is placed right below the sun and thus, it tends to receive the maximum radiation across the year. While the poles are the coldest regions of the Earth because due to Earth's titled axis, they receive very few sun rays for a certain time of the year. Thus, <u>if we move away from the equator, we are likely to receive less radiation from the sun as the sun keeps getting farther while moving away from the equator</u>.

Nitroglycerin, used both in medicine and as an explosive, can be prepared by the carefully controlled reaction of glycerol (C3H8

vesna_86 [32]

The mass of nitric acid (HNO₃) required for the production of 2.8 g of nitroglycerin? (C₃H₅N₃O₉) is 2.33 g

We'll begin by calculating the mass of HNO₃ that reacted and the mass of C₃H₅N₃O₉ produced from the balanced equation. This can be obtained as follow:

C₃H₈O₃ + 3HNO₃ —> C₃H₅N₃O₉ + 3H₂O

Molar mass of HNO₃ = 1 + 14 + (16×3)

= 1 + 14 + 48

= 63 g/mol

Mass of HNO₃ from the balanced equation = 3 × 63 = 189 g

Molar mass of C₃H₅N₃O₉ = (12×3) + (1×5) + (14×3) + (16 × 9)

= 36 + 5 + 42 + 144

= 227 g/mol

Mass of C₃H₅N₃O₉ from the balanced equation = 1 × 227 = 227 g

<h3>SUMMARY:</h3>

From the balanced equation above,

227 g of C₃H₅N₃O₉ were produced by 189 g of HNO₃.

Finally, we shall determine the mass of HNO₃ that will produce 2.8 g of C₃H₅N₃O₉. This can be obtained as follow:

From the balanced equation above,

227 g of C₃H₅N₃O₉ were produced by 189 g of HNO₃.

Therefore,

2.8 g of C₃H₅N₃O₉ will be produce by = $\frac{2.8 * 189}{227} \\\\$ = 2.33 g of HNO₃

Thus, the mass of nitric acid (HNO₃) required for the production of 2.8 g of nitroglycerin? (C₃H₅N₃O₉) is 2.33 g

Determine the volume of 0.150 M NaOH solution required to neutralize 145 mL of a 0.25 M HCl solution. The neutralization reactio

QveST [7]

Answer:-

241.66 mL

Explanation:-

Volume of HCl = 145 mL / 1000 = 0.145 L

Strength of HCl = 0.25 M

Number of moles of HCl = Strength x volume

= 0.25 M x 0.145 L

= 0.03625 moles

According to the balanced chemical equation

NaOH(aq) + HCl(aq) → H 2 O(l) + NaCl(aq)

1 mol of HCl reacts with 1 mol of NaOH.

∴0.03625 moles of HCl reacts with 0.03625 moles of NaOH.

Strength of NaOH = 0.15 M

Volume of NaOH = Number of moles / strength

= 0.03625 moles / 0.15 M

= 0.24166 L x 1000

= 241.66 mL
