The given reactions are; First reaction is a displacement reaction, Second
reaction is the production of MgO and hydrogen gas.
1. The missing component is Cl₂.
2. The missing component is H₂O.
Reasons:
1. The given reaction can be presented as follows;
? + 2NaBr [tex]\longrightarrow[/tex] 2NaCl + Br₂
The above reaction has both 2 Na and 2 Br on the side of the reactants, and 2 Na, 2 Br, and 2 Cl on the side of the products, therefore
The missing component is Cl₂
2. The possible given reaction is presented as follows;
Mg + ? HBr [tex]\longrightarrow[/tex] MgO + H₂
The elements in the reactant side of the reaction are one Mg and unknown element (?)
The elements in the product side are one Mg one O and two H
Therefore;
The the missing elements in the reactants are, 2 H and 1 O, which gives;
The missing component = H₂O

Which best describes the first law of thermodynamics as compared to the second law of thermodynamics? The first law describes how thermal energy is conserved but not the direction it moves. The first law describes the direction thermal energy moves but not how it is conserved. The first law describes how thermal energy can be created but not how it can be destroyed. The first law describes how thermal energy can be destroyed but not how it can be created.
The statement which best describes the difference between the first law of thermodynamics in comparison with the second law of thermodynamics is that: A. The first law describes how thermal energy is conserved but not the direction it moves.
The First Law of Thermodynamics states that energy can neither be created nor destroyed but it can only be transformed (converted) from one form to another such as potential energy to kinetic energy. Thus, thermal energy is always conserved according to the First Law of Thermodynamics.
On the other hand, the Second Law of Thermodynamics states that the entropy (disorderliness) of an isolated system always increases and can never be decreased. Thus, the direction of an energy is described by the Second Law of Thermodynamics.
In conclusion, the difference between the First Law of Thermodynamics in comparison with the Second Law of Thermodynamics is that the first law describes how thermal energy is conserved but not the direction in which thermal energy moves.

why is it important to reduce reuse and recycle plastic materials to save the environment?
Answer:
Plastic materials do not decompose easily and most end up in the ocean where they can potentially harm animals. Some plastics also release carcinogens when burnt. By reducing its usage, we look for a more sustainable alternative to plastic materials. Reuse old plastic containers, bags, etc. if they can are still in good condition. Recycling will repurpose plastics that are no longer in proper condition to be used how it was originally intended to be.
What is the value of x in the equation 2 (6 x 4) minus 6 2 x = 3 (4 x 3) 1? 1 3 4 6.
Answer:
4
Step-by-step explanation:
2 (6 x + 4) - 6 + 2 x = 3 (4 x + 3) + 1
12x + 8 - 6 + 2x = 12x + 9 + 1
12x + 2 + 2x = 12x + 10
2x + 2 = 10
2x = 10 - 2
2x = 8
x = 4

Explanation:
Assume the blood pressures of 10 people were measured before and after sleeping for the night. What is the corresponding critical t-value for a one-tailed, paired-samples t test with an alpha level of 0. 05 (5%). Please report your answer as an absolute value and include three decimal places.
Using a t-distribution table or a t-critical value calculator, the critical value for a one- tailed t - test for the sample given at 0.05 α-level would be 1.833
The critical value for a one-tailed, paired sample t test can be defined thus :
[tex]t_{critical} = t_{α, df-1} [/tex] Sample size, n = 10The degree of freedom , df for a 1 - tailed t-test is calculated using the relation :
df = n - 1Hence,
Degree of freedom, df = n - 1 = 10 - 1 = 9
Using a Tcritical value calculator or a t - distribution table :
[tex]t_{critical} = t_{0.05, 9} = 1.833 [/tex]
Therefore, the critical value for a one - tailed test at 0 05 level of confidence would be 1.833.

A probe orbiting Venus exerts a gravitational force of 2. 58 × 103 N on Venus. Venus has a mass of 4. 87 × 1024 kg. The mass of the probe is 655 kilograms. The gravitational constant is 6. 67 × 10-11 N*m2/kg2. To three significant digits, the probe is × 106 m from the center of Venus.
Answer:
9.08
Explanation:
To solve for the distance between the probe and the center of Venus, use the formula:
[tex]\mathrm{F = \frac{G\: m1 \:m2}{r^2}}[/tex]
Plugin the values:
G =
[tex]6.67\times10^{-11} \mathrm{\frac{m3}{kg\: s2}}[/tex]
[tex]\mathrm{F} =2.58 \times 10^3\mathrm{N}[/tex]
[tex]\mathrm{m1 = 4.87 \times 10^{24}\:kg}[/tex]
[tex]\mathrm{m2 = 655\: kg}[/tex]
Hence:
[tex]\mathrm{F = \frac{G\: m1 \:m2}{r^2}}[/tex]
[tex]2.58 \times 10^{23} = 6.67 \times 10^{-11} (4.87 \times 10^{24})[/tex]

Which statements correctly characterize asoka's reign? select all correct answers.
Answer:
Roads, hospitals, and monuments were built.
Buddhism spread through missionary monks.
Explanation:
Asoka was the founder of the Moorish dynasty, and extended the kingdom to the western half of northern India. His endeavor, accompanied by fearsome bloodshed, provoked profound spiritual upheavals at Asoka, after which he embraced Buddhism, which had appeared in Magadha two centuries earlier. Since then, the cruel Asoka has become known as the godly Asoka. In the words of the emperor himself, since then his sound was no longer booming, but the voice of dharma.
During his rule, he pursued an official policy of non-violence. The unnecessary killing and mutilation of animals has been abandoned, such as hunting for hunting and stamping.
Asoka also showed mercy to the captives, allowing them a day of freedom each year, and providing ordinary citizens with free education at universities. He treated subjects as equals regardless of religion, politics or caste and made free hospitals for both humans and animals. Asoka defined the main principles of nonviolence, tolerance of sects and opinions, obedience to parents, respect for teachers and priests, human treatment of servants (slavery did not even exist in India at that time) and generosity to all. These reforms are described by Asoka's edicts.
