Answer:
64 kg
Explanation:
The computation of the number of kg need to ordered is shown below:
As we know that
Now as we know that
1 mole of 
generated from 1 mole of 
Now
26g of generated from 64g of
And,
26kg of generated from
= 
= 64kg
Hence, the number of kg that required for ordering the calcium carbide is 64 kg
Answer:
90 °C
Explanation:
First, we must know the specific heat capacity of water, which is defined as the energy required to heat 1 gram of water by one degree Celsius. The specific heat capacity of water is 1 cal·g⁻¹°C⁻¹.
The equation we will use is Q = mcΔt, where Q is the heat energy, m is the mass, c is the specific heat capacity, and Δt is the temperature change. We will rearrange the equation to solve for Δt and substitute the values:
Δt = Q / (mc) = (90 kcal)(1000 cal/kcal) / (1 kg)(1000 g/kg)(1 cal·g⁻¹°C⁻¹) = 90 °C
