Percentage Weight-in-volume is defined as the <em><u>number of grams of a solute in a 100 ml (milliliters) solution.</u></em>
<u />
<u>Percentage Weight-in-volume</u> can tell us about the <em>degree of concentration of a given solution.</em>
<em><u /></em>
The solute can be <em>crystalline or non-crystalline in nature.</em>
<em></em>
The <u>number of grams of glucose</u> present in a <u>5% glucose solution</u> is 5 grams.
- This question is based on a Percentage Weight-in-volume. The formula states that:
a% of a glucose solution =<u> a grams of glucose in a 100 mL solution</u>
Hence, 5% glucose solution = 5 grams of glucose / 100 mL solution
Therefore, the <u>number of grams of glucose</u> present in a <u>5% glucose solution</u> is 5 grams.

A. NUCLEAR FUSION is the combination of two atomic nuclei in order to create an atom that in turn creates energy.
A.1 DISADVANTAGES
1. Expensive Construction Costs- To be able to put up such powerhouse, it needs ostentatious financial support to create a facility and gather experts and scientists.
2. Energy Input vs Energy Output- To be able to fuse the two nuclei together, there is a great demand for high levels of heat. Thus to be able to produce large amount of energy, it also needs a large amount of thermal energy which is not reasonable enough.
A.2 ADVANTAGES
1. Barely Any Waste- the only by product of nuclear fusion is helium and it is non toxic. This does not cause any harm to the environment and to people.
2. Unlimited Fuel- All of the components needed to produce energy can be made. Deuterium, which is the main ingredient needed to supply a truly unlimited and sustainable energy supply, can be distilled from the sea water.
B. NUCLEAR FISSION- refers to the process of splitting of the nucleus of an atom into several smaller particles to produce free neutrons and lighter elements.
B.1 DISADVANTAGES
1. It can be dangerous for employees- Radiation which is one of the byproducts of nuclear fission can be harmful to the personnel working within its premises.
2. It has high initial expenses- Nuclear power plants needs a specialized equipment for it to become functional.
B.2 ADVANTAGES
1. It helps minimize environmental pollution- Nuclear power plants can produce large amounts of energy while consuming relatively minimal amount of fossil fuel. To explain further, consumption and usage of fossil fuel poses adverse effect in the environment because it can emit carbon dioxide and other harmful chemicals.
2. It helps reduce global warming- If the world would opt for nuclear fission, then there would be less greenhouse gasses in the atmosphere. This in turn would mitigate global warming.
Answer:
positive
Explanation:
proton is a subatomic particle with a postive charge on it.
hope this helps!!! ☺️
Answer:
option b. B3+
Explanation:
Boron takes the 5th position on the periodic table, therefore it has 5 electrons....2 on the inside and 3 on the outside. when it lost it 3 external electrons, it become positively charged with the amount of electron it loses.
