The mass of water that will be needed to make the solution is calculated as below
% solution = mass of the solute/mass of the solvent(water) x100
% solution = 5% = 5/100
mass of the solute =0.377 g
mass of the solvent = ?
let the mass of the solvent be represented by Y
= 5/100 =0.377/y
by cross multiplication
5y= 37.7
divide both side by 5
y =7.54 grams
Answer:
A.
Carbon dioxide
Explanation:
In a tissue that metabolizes glucose via the pentose phosphate pathway, C-1 of glucose would be expected to end up principally in Carbon dioxide

Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils whereas erosion is the movement of weathered materials from one area to the other.
Erosion moves weathered materials and it causes them to change position. For example loose chips of rocks broken down as the rock weakens through alternate wetting and drying in tropical regions will remain in-situ until the agents of erosion comes to carry them away. The breaking is weathering and the carrying is erosion.

Examples of mechanical weathering:
- Frost action
- Pressure release
Examples of chemical weathering:
There are two types of weathering:
- In mechanical weathering, a rock disintegrates into smaller chunks by the action of wind, water and glacier. For example in temperate and polar regions, water within rocks freezes. When water freezes it expands and causes tension within the rock. When temperature drops, water melts and the tension is relieved. This process causes a rock to crack. The crack will eventually become wider with time.
- In chemical weathering, a rock decomposes by the action of chemicals formed in the rock. In karst regions where limestone forms, combination of rain water and carbon dioxide forms weak carbonic acid that reacts with calcite in limestone.

An earthquake's magnitude is a measure of how much energy an earthquake releases. Typically, the richter scale is used.
