Explanation:
Last month, he wrote 9 reports, and this month he wrote 28 reports. To find how many he wrote over the past two months, add his reports from last month and this month.
last month + this month
9 reports +28 reports
37 reports
So, he wrote 37 reports, or choice D
Answer:
<h3>The man's average body temp. will fall by 0.6°C to 38.4°C</h3>
Explanation:
The enthalpy (heat content) of the water, using a datum of 0°C, is
Hw = Mw kg x Cp,w (specific heat capacity kJ/kg °C) x Tw °C
= 1 kg x 4.18 kJ/kg°C x 3°C = 12.5 kJ
Hman (pre drink) = 68 kg x 3.6 kJ/kg/°C x 39°C = 9547 kJ
So Hman (post drink) = H (pre drink) + Hw = 9547 + 12.5 = 9559.5 kJ because no heat is lost immediately.
But Hman (after drink) has mass 68 + 1 = 69 kg
Also his new Cp will be approx (3.6 x 68/69) + (4.18 x 1/69) = 3.608 kJ/kg°C
So Hman = 9559.5 kJ (from above) = 69 kg x 3.608 kJ/kg°C x Tnew
Therefore the man's new overall temp. = 38.4°C which is a drop of 0.6°C
Answer:
Explanation:
CH4 + 2O2 --> CO2 + 2H2O
1mol generates 2 moles of H2O
Therefore 6 Moles produce 12 moles of H2O
Ca + Cl2 = CaCl₂
