<span>Near Earth's surface, the distance between the object that is falling and the center of Earth does not change very much. Thus, the force given by the law of universal gravitation depends only on the mass of the object that is falling.</span>

Requiring industries to recycle 25% of plastics in their manufacturing process is an example of: Risk communication Risk assessm
Tomtit [17]

Answer:

Risk management

Explanation:

Risk communication is exchange of the advice, real-time information and the opinions between the experts and the people which are facing threats to their economic, health, or well-being.

Risk assessment is overall process where the hazards and the risk factors which have potential to cause the harm is identified.

Risk perception is subjective judgement which people/ experts make about characteristics and the severity of the risk.

Risk management is evaluation, identification and prioritization of the risks followed by the coordinated and the economical application of the resources to monitor, minimize and control probability of the unfortunate events.

Thus, Option D is correct because in risk management, a Quantitative Solution is given to decrease risk level like to recycle the plastic.

The decomposition of water produces 50g of Hydrogen gas and 75 g of oxygen gas. How much water
Lostsunrise [7]

84.24 g of water (H₂O)

Explanation:

We have the following chemical reaction:

2 H₂O → 2  H₂ + O₂

Now we calculate the number of moles of products.

number of moles = mass / molar weight

number of moles of H₂ = 50 / 2 = 25 moles

number of moles of O₂ = 75 / 32 = 2.34 moles

We see from the chemical reaction that for every 2 moles of H₂ produced there are 1 mole of O₂ produces for every 25 moles of H₂ produced there are 12.5 moles of O₂ but we only have 2.35 moles of O₂ available. The O₂ will be the limiting quantity from which we devise the following reasoning:

if        2 moles of H₂O  produces 1 mole of O₂

then  X moles of H₂O  produces 2.34 mole of O₂

X = (2 × 2.34) / 1 = 4.68 moles of H₂O

mass = number of moles × molar weight

mass of H₂O = 4.68 × 18 = 84.24 g
