Answer:
Explanation:
The given equation is not correctly balanced. However the number of each type of atoms on right side are,
Mg = one magnesium atom
S = two sulfur atom
Cu = two cuppor atoms
Cl = two chlorine atoms
Chemical equation.
MgS + CuCl₂ → CuS + MgCl₂
Balance chemical equation:
2MgS(aq) + 2CuCl₂(aq) → 2CuS(s) + 2MgCl₂(aq)
In case of balance chemical equation number of each type of atoms on right side are,
Mg = two magnesium atom
S = two sulfur atom
Cu = two cuppor atoms
Cl = four chlorine atoms (because two chlorine atom form one chlorine molecule)
Mulch includes compost, grass clipping, leaves or other organic matter which increaese the fertility of soil by providing the necessary nutrients.
Volume of much used
To converting into m^3, divide it by 10^6
Thus, riya is applying mulch at rate of 0.25 m^3 per m^2 of garden.
Neutral, because anything too acidic or basic would kill a person
Answer:
126000J
Explanation:
From the question given, we obtained the following information:
M = 1500g
C = 4.2J/g°C
ΔT = 20°C
Q =?
Q= MCΔT
Q = 1500 x 4.2 x 20 =
Q = 126000J
