Answer:
125.5 ×10^-3 m^3= 0.1255 m^3
Explanation:
Volume=5.6mol×22.414dm^3
=125.5dm^3
Answer:
The pH is approximately: 2.1549
Explanation:
pH = - log(0.007)
Water infiltrates faster into soils that are mostly sand than into those that are mostly clay or silt. ... When the soil is completely saturated, additional water moves slowly down through the unsaturated zone to the saturated zone, replenishing or recharging the groundwater.
The mass of the air sample is calculated using the below
Q(heat)=M(mass) x C(specific heat capacity) x delta T(change in temperature)
Q= 120.j
M=?
C= 1.0j/g/c
delta T =45.0-33.2=11.8 c
by making M the subject of the formula
M=Q/C delta T
= 120 j/ 1.0 j/g/c x11.8 c=10.17 grams
