Hope this Helps!!Hope this Helps!!:)There are two types of chemical compound one is covalent compound and another is ionic compound in chemistry. In ionic bonds, electrons are completely transferred. Therefore, the name of CH[tex]_4[/tex] and CO[tex]_2[/tex] are Methane and Carbon dioxide respectively.
What is chemical Compound?Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.
Covalent compounds are formed by covalent bond and ionic compounds are formed by ionic bond. Covalent bond is formed by sharing of electron and ionic bond are formed by complete transfer of electron. Ionic bonds are stronger than covalent bonds. The melting and boiling points are higher in ionic compounds.

which substance will evaporate first???????????????????
Answer:
I think it would be a liquid.
Explanation:
If the temperature hits a certain point, it will turn to ice. If the ice gets exposed to heat, it will melt and return back to it's natural form, a lqiuid. If the liquid is exposed to enough heat, it will evaporate. Not sure if this is right, but I tried my best!

Example 1 How much water (in grams) is produced when 65.2 grams of Calcium carbonate react with phosphoric acid to form calcium phosphate, water, and carbon dioxide?
Answer:
11.75 g H2O
Explanation:
3CaCO3 + 2H3PO4 --> Ca3(PO4)2 + 3H2O + 3CO2
MM H2O = 18.02 g/mol
MM CaCO3 = 100 g/mol
? g H2O = mass CaCO3 x (1 mol CaCO3/MM CaCO3) x (3 moles H2O/3 moles CaCO3) x (MM H2O / 1 mol H2O) = (65.2/100) x 18.02 = 11.75 g H2O

Which of these compounds has the largest percentage by mass of nitrogen? NO N2O NO2 N2O3
The largest mass percentage of nitrogen in NO. Therefore, option (A) is correct.
What is the mass percentage?The percentage by mass of an element in a chemical compound can be described as the number of parts by mass of the element contained in 100 parts by mass of a chemical compound.
The mass percentage of an element can be determined in two steps:
First, calculate the molar mass of the compound and then the percentage of each element by dividing the total mass of the element present in the compound by the molecular mass of the compound multiplied by 100.
Given, the molecular formula of the compound is NO.
The molecular mass of the NO = 30 g/mol
The mass percentage of the Nitrogen = (14/30) × 100 = 46.67 %
the molecular formula of the compound is NO₂.
The molecular mass of the NO = 46 g/mol
The mass percentage of the Nitrogen = (14/46) × 100 = 30.4 %
the molecular formula of the compound is N₂O.
The molecular mass of the NO = 44 g/mol
The mass percentage of the Nitrogen = (14/44) × 100 = 31.81 %
the molecular formula of the compound is N₂O₃.
The molecular mass of the NO = 76 g/mol
The mass percentage of the Nitrogen = (28/76) × 100 = 36.84 %

A seedling is planted in soil that does not have any clay. What will most likely happen to the plant?
Answer:
Explanation:
Under good conditions the seedling can thrive in soil that does not have any clay as long as it gets the proper nutrients and right amount of sunlight/water that it needs. Clay in soil can provide the nutrients necessary for seedlings to thrive but can also cause many negatives. One such con of using clay is that it does not absorbe water very well, this ultimately causes the soil to become waterlogged and drowns the plants as no oxygen can pass through. This would ultimately kill the plants.

How many grams are in 3.00 moles of carbon
Answer: Ok I think The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Carbon, or 12.0107 grams. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between moles Carbon and gram. 12 grams
This means that the atomic mass or atomic weight (12 grams) of carbon is equal to exactly 1 mole of carbon.
hope this helps have a awesome night/day❤️✨
Explanation:
There are 36 grams in 3.00 moles of carbon.
HOW TO CALCULATE MASS:
The mass of a substance can be calculated by multiplying the number of moles by its molar mass. That is;mass (g) = no. of moles (mol) × molar mass (g/mol)According to this question, 3 moles of carbon was given. The mass can be calculated as follows:atomic mass of Carbon = 12g/molMass = 12g/mol × 3molMass = 36g.

how heart attacks and Strokes caused by cholesterol
With high cholesterol, you can develop fatty deposits in your blood vessels. Eventually, these deposits grow, making it difficult for enough blood to flow through your arteries. Sometimes, those deposits can break suddenly and form a clot that causes a heart attack or stroke.
Answer:
Cholesterol is a waxy substance found in your blood. Your body needs cholesterol to build healthy cells, but high levels of cholesterol can increase your risk of heart disease.
With high cholesterol, you can develop fatty deposits in your blood vessels. Eventually, these deposits grow, making it difficult for enough blood to flow through your arteries. Sometimes, those deposits can break suddenly and form a clot that causes a heart attack or stroke.
Explanation:
High cholesterol can cause a dangerous accumulation of cholesterol and other deposits on the walls of your arteries (atherosclerosis). These deposits (plaques) can reduce blood flow through your arteries, which can cause complications, such as:
Chest pain. If the arteries that supply your heart with blood (coronary arteries) are affected, you might have chest pain (angina) and other symptoms of coronary artery disease.
Heart attack. If plaques tear or rupture, a blood clot can form at the plaque-rupture site — blocking the flow of blood or breaking free and plugging an artery downstream. If blood flow to part of your heart stops, you'll have a heart attack.
Stroke. Similar to a heart attack, a stroke occurs when a blood clot blocks blood flow to part of your brain.

If 80mg of a radioactive element decays to 10mg in 30 days, what is the elements
half life in minutes?
Answer: 10 minutes
Explanation:
ln(No/N) = kt
No = 80 mg
N = 10 mg
t = 30 min
solve for k, then
k = 0.693/t1/2
Substitute k from above and solve for t1/2
10 min is correct.

A hockey puck is hit with a large force. The puck moves at a high speed as it slides over the ice.
What happens according to Newton’s first law of motion?
A) The puck does not lose any speed because ice is a very slippery surface.
B) The puck gradually slows down because mass makes objects slow down.
C) The puck gradually slows down because friction would be acting on it.
D) The puck does not lose any speed because once an object starts moving, the force of friction would no longer apply to it.
Answer:
C) The puck gradually slows down because friction would be acting on it.
Explanation:
It would be C because the puck would be scraping the ice and when it's scraping it slowly losses its speed because the ground is pushing it lightly
