You put two ice cubes in a glass and fill the glass to the rim with water. As the ice melts, the water level

omeli [17]

You put two ice cubes in a glass and fill the glass to the rim with water. As the ice melts, the water level remains the same.

Answer: Option D

<u>Explanation:</u>

As the ice is already in the water, and that has melted, there is no addition of volume into the glass. The water spills out if extra volume is added to the container. Hence, as there is no more volume added, there should be no change seen in the level of water.

The water level stays the same. This is because either it is a solid or liquid, the volume remains same. The volume of ice before melting is same as the volume of water, when melted into.

Question 2 Ammonium phosphate NH43PO4 is an important ingredient in many fertilizers. It can be made by reacting phosphoric acid

Mama L [17]

Answer:

The answer is 12.27 g (NH4)3PO4

Explanation:

Step 1: balance the chemical equation:

H3PO4 + 3NH3 → (NH4)3PO4

step 2: the molar masses of each of the reagents and products are calculated using the periodic table:

H3PO4:

3 atoms of H: 3x1=3 g/mol

1 atom of P: 1x30.97=30.97 g/mol

4 atoms of O: 4x16=64 g/mol

Molar mass=3+30.97+64=97.97 g/mol

3NH3:

3 atoms of N: 3x14=42 g/mol

9 atoms of H: 9x1=9 g/mol

Molar mass=42+9=51 g/mol

(NH4)3PO4:

3 atoms of N: 3x14=42 g/mol

12 atoms of H: 12x1=12 g/mol

1 atom of P: 1x30.97=30.97 g/mol

4 atoms of O: 4x16=64 g/mol

Molar mass=42+12+30.97+64=148.97 g/mol

we make a rule of three to calculate the amount of ammonium phosphate:

51 g NH3------------------148.97 g (NH4)3PO4

4.2 g NH3-----------------x g (NH4)3PO4

Clearing the x, we have:

$x g (NH4)3PO4 = \frac{(4.2 g NH3)x(148.97 g (NH4)3PO4)}{51 g NH3}=12.27 g (NH4)3PO4$

A long, cylindrical solenoid with 100 turns per centimeter has a radius of 14.7 cm. If the current through the solenoid changes

oee [108]

Answer:

Explanation:

Given:

dI/dt = 6.21 A/s

n = N/l

= 100 turns/cm

= 100 turns/cm × 100 cm/1 m

Radius, r = 14.7 cm

= 0.147 m

Inductance, L = uo × n^2 × A × l

L/l = 4pi × 10^-7 × (100 × 100)^2 × pi × 0.147^2

= 8.53 H

Emf, E = L × dI/dt

E/l = L/l × dI/dt

= 8.53 × 6.21

= 52.98 V/m
