Answer:
Mass of water == 1.71 g
Explanation:
Given data:
Initial temperature of water = 10°C
Final temperature of water = 50°C
Energy absorbed = 286 J
Mass of water = ?
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Specific heat capacity of water is 4.18 J/g.°C
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 50°C - 10°C
ΔT = 40°C
by putting values,
286 J = m × 4.18 J/g.°C × 40°C
286 J = m × 167.2 J/g
m = 286 J / 167.2 J/g
m = 1.71 g
Answer: The force of attraction occurring between two masses.
Answer:
1.57694 L
Explanation:
To convert from mL to L, you simply divide the value by 1000.

Answer:</h3>
A(l)→A(aq) -Non electrolyte
BC(aq)⇌ B+(aq)+C−(aq) - Weak electrolyte
DE(aq)→D+(aq)+E−(aq) - Strong electrolyte
XY(s)→X+(aq)+Y−(aq) -Strong electrolyte
Z(s)→Z(aq) - Non-electrolyte
<h3>
Explanation:</h3>
- An electrolyte is a substance that is either in a molten or aqueous form that ionizes when dissolved in water and conducts an electric current when passed through it.
- Non-electrolytes, therefore, do not ionize when dissolved in water to form free ions and thus do not conduct electric current.
- Electrolytes may be classified as strong or weak electrolytes.
- Strong electrolytes such as strong acids and bases are those electrolytes that ionize completely to form ions that are responsible for the conduction of electricity.
- Weak electrolytes on the other hand partially ionize to yield ions. They include weak acids such as acetic acids and weak bases.
Answer:
1 ms = 1000000000 ps
convert 6.25 ms to ps:
6.25ms = 6.25× 1000000000 ps = 6 250 000 000 ps
