Answer:

1. P-Type, 2. Paramagnetic, 3. Lanthanides and Actinides, 4. Carbon, hydrogen, oxygen, and nitrogen

Explanation:

Answer:

There are pros and cons, I will explain mostly pros. After all the pros outweigh the cons.

Explanation:

Increasing the minimum wage can be letting people work less or earn more. This can have a major impact on the economy in America. It can reduce poverty within some families households. A con concerning this though is that people who work for low pay can lose their jobs and their family can become poor. It can also affect the federal minimum wage.

Hopefully this helped you out a lot. Please make sure to make my answer brainliest. Have a great rest of your day or night

Answer:

Minimum wage increases allow people to work less and earn more. This may have a significant influence on the American economy. It can help some families get out of poverty. People who labor for little compensation risk losing their employment and being unable to provide for their families, which is a drawback. As a result, the federal minimum wage may also be affected.

Answer: I think the answer is The muscle contractions result in physical changes, while the action of the peptidase results in chemical changes.

Explanation: Because the muscles would make the food smaller and the enzymes have a chemical change to it because it changes the molecules in the food.

The chemical processes in food digestion results in the formation of new

substances.

The statement that best describes the changes in food during digestion is;

The churning of the food is a physical process, which results in physical changes while the peptidase results in chemical changes of the food.

Reasons:  

The given processes in the digestion of food are;

Stomach: Food churning is the process by which the small intestine vigorously turns ingested food.

Small intestine: The action of the peptidase enzyme is to increase the rate of the digestion of food.

Therefore;

The churning of the food is a physical process, which results in physical changes while the peptidase results in chemical changes of the food.

Answer:497J/kg/K

Explanation:

Use the equation: Q=mS◇T

According to specific heat capacity, the specific heat of glass is 0.4970 J/gK.

Specific heat capacity is defined as the amount of energy required to raise the temperature of one gram of substance by one degree Celsius. It has units of calories or joules per gram per degree Celsius.

It varies with temperature and is different for each state of matter. Water in the liquid form has the highest specific heat capacity among all common substances .Specific heat capacity of a substance is infinite as it undergoes phase transition ,it is highest for gases and can rise if the gas is allowed to expand.

It is given by the formula ,

Q=mcΔT

Substituting values in above equation, c=Q/mΔT, C=840/65×26=0.4970 J/gK.

Thus, the specific heat of glass is 0.4970 J/gK.

Explanation:

CO has two C-O bonds. The dipoles point in opposite directions, so they cancel each other out. Thus, although CO₂ has polar bonds, it is a nonpolar molecule. Therefore, the only intermolecular forces are London dispersion forces.

The % yield of Ca(OH)₂ : 62.98%

Percent yield is the compare of the amount of product obtained from a reaction with the amount you calculated

General formula:

Percent yield = (Actual yield / theoretical yield )x 100%

An actual yield is the amount of product actually produced by the reaction. A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients

Reaction

CaO + H₂O ⇒ Ca(OH)₂

mass CaO= 4.2 g

mol CaO(MW=56,0774 g/mol) :

[tex]\tt mol=\dfrac{mass}{MW}\\\\mol=\dfrac{4.2}{56,0774 g/mol}\\\\mol=0.075[/tex]

mol Ca(OH)₂ based on mol CaO

mol ratio CaO : Ca(OH)₂,= 1 : 1, so mol Ca(OH)₂ = 0.075

mass Ca(OH)₂(MW=74,093 g/mol) ⇒ theoretical

[tex]\tt mass=mol\times MW\\\\mass=0.075\times 74,093 g/mol\\\\mass=5.557~g[/tex]

% yield :

[tex]\tt =\dfrac{actual}{theoretical}\times 100\%\\\\=\dfrac{3.5}{5.557}\times 100\%\\\\=62.98\%[/tex]

CH4(g) + 2O2(g) -------> CO2(g) + 2H2O(g)

Explanation:

Even though the question is incomplete because the equations are missing. However, one thing that is clear from the question is that the reaction is a combustion reaction.

A combustion reaction is a type of reaction that produces heat and light. The mixture of methane and oxygen yielded a brief, large flame which shows that combustion has taken place according to the equation shown above.
