Specific heat of water, C = 4.18 J/g. °C
From question, Mass of water= 7g
Temperature difference = 180 degree Celsius
We know by formula,
Heat (Q)= c* m(mass) * T (change in temperature)
So, Q= 4.18 J/g. °C *7g * 180 °C
=5266.8 J
Copper oxidizes in moist air
2Cu + CO₂ + O₂ + H₂O = (CuOH)₂CO₃
copper reacts with concentrated acids, for example, with nitric acid
Cu + 4HNO₃ = Cu(NO₃)₂ + 2NO₂ + 2H₂O
copper reacts with chlorine
Cu + Cl₂ = CuCl₂
copper reacts with oxygen when heated
2Cu + O₂ = 2CuO

Answer:
Balanced chemical equation:
CH₄ + 2O₂ → 2H₂O + CO₂
Explanation:
Chemical equation:
CH₄ + O₂ → H₂O + CO₂
Balanced chemical equation:
CH₄ + 2O₂ → 2H₂O + CO₂
Step one:
CH₄ + O₂ → H₂O + CO₂
C = 1 C = 1
H = 4 H = 2
O = 2 O = 3
Step 2:
CH₄ + 2O₂ → H₂O + CO₂
C = 1 C = 1
H = 4 H = 2
O = 4 O = 3
Step 3:
CH₄ + 2O₂ → 2H₂O + CO₂
C = 1 C = 1
H = 4 H = 4
O = 4 O = 4
Answer:
Quarts of blood = 72000
Quarts of urine = 720
Explanation:
<h3><u>Given</u>;</h3>
- Each day, the average person's
- kidneys filter around 200 quarts of blood.
- About 2 quarts of urine is produced in the
- process.
<h3><u>To </u><u>Find</u>;</h3>
- In one year the average person's kidney filter quarts of blood and quarts of urine.
Here, we know that
1 year = 365 days
For blood
200 × 365 = 72000
For urine
2 × 365 = 720
Thus, The average person's kidney filters 72000 quarts of blood and 720 quarts of urine.
