Answer: The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides
Explanation:
The moon's gravity affects the oceans nearest the moon because the moon's gravity pulls water into a tidal bulge is a true statement.
What is tidal force?The tidal force is the result of the moon's gravitational pull.
The tidal force causes Earth—and its water—to bulge out on its closest and furthest sides from the moon. High tides cause these water bulges.
Thus, the statement is correct.

How does the melting of ice caps near the North Pole affect the salinity of the ocean?
Salinity decreases because freshwater flows into the ocean
Salinity increases because of the stored pockets of air and salt
Salinity increases because salt from the ice caps flows into the ocean
There is no change in the ocean’s salinity with this process
Answer:
A.
Explanation:
melting of ice will increase water in oceans due to which water in oceans will increase and salinity will decrease. hence, melting of ice caps near the north pole affects salinity of the ocean

Name two metals which will not liberate hydrogen from
dilute tetraoxosulphate(vi) acid.
To solve such this we must know the concept of double displacement reaction. Therefore, copper (Cu) and silver (Ag) would not liberate hydrogen from dilute tetraoxosulphate(vi) acid.
What is chemical reaction?Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.
Copper (Cu) and silver (Ag) would not liberate hydrogen because they are less reactive than hydrogen since their standard reduction potential is higher.
Therefore, copper (Cu) and silver (Ag) would not liberate hydrogen from
dilute tetraoxosulphate(vi) acid.

What are one advantage and one disadvantage of sexual reproduction?
What is one advantage and one disadvantage of asexual reproduction?
Answer:asexual- Energy is not required to find a mate. Offspring are genetic clones. A negative mutation can make asexually produced organisms susceptible to disease and can destroy large numbers of offspring. Some methods of asexual reproduction produce offspring that are close together and compete for food and space.
Explanation:During sexual reproduction the genetic material of two individuals is combined to produce genetically diverse offspring that differ from their parents.

Mg (s) + 2 HCl (aq) --> MgCl2 (aq) + H2 (g)
Use the equation above to determine the number of grams of magnesium chloride, MgCl2 , that can be produced if 4.00 moles of HCl (hydrochloric acid) react. please show all work and record your answer with proper units and significant figures.
Pls help
Answer:
m = 190. g MgCl2
Explanation:
Use a molar ratio to get the # of moles MgCl2 produced from 4.00 mol of HCl:
4.00 mol HCl × (1 mol MgCl2/2 mol HCl) = 2.00 mil MgCl2
So 2.00 moles of MgCl2 will be produced. To find the mass in grams, use the molar mass of MgCl2:
2.00 mol MgCl2 × (95.211 g MgCl2/1 mol MgCl2)
= 190. g MgCl2

When a cube of manganese oxide was added to a solution of hydrogen peroxide, water and oxygen were produced. Manganese oxide was not used up in the reaction. Which of the following is likely to increase the rate of the reaction? (5 points)
Reducing the mass of the cube
Using a smaller amount of solution
Smashing the cube into pieces
Chilling the hydrogen peroxide solution
Answer:
Smashing the cube into pieces
Explanation:
The reason for this is that if we were to smash the cube we would have a larger surface area which means more manganese oxide would be dissolving per second which means we would have a faster reaction rate where if we were to chill the peroxide it would dissolve slower which in turn slows the reaction. For example a spoonful of granulated sugar will react with water faster than a sugar cube.
The rate of the reaction is increased by smashing the cube into pieces. C is the correct answer.
What is the reaction rate?The reaction rate, also known as the rate of reaction, is the rate at which a chemical reaction occurs.
It is typically classified as proportional to the change in product concentration per unit time and the change in reactant concentration per unit time. Different chemical reactions have different reaction rates.
The amount of reactants, the temperature, and the catalyst all influence the reaction rate.
When a cube of manganese oxide was added to a solution of hydrogen peroxide, water and oxygen were produced, just as in the given reaction. The reaction did not deplete manganese oxide.
The reaction will be altered by smashing the cube into pieces as the it can boost appropriate conditions for the reaction.
Thus, C is the correct answer.

Vitamin B12, cyanocobalamin, is essential for human nutrition. It is concentrated in animal tissue but not in higher plants. Although nutritional requirements for the vitamin are quite low, people who abstain completely from animal products may develop a deficiency anemia. Cyanocobalamin is the form used in vitamin supplements. It contains 4.34% cobalt by mass. Calculate the molar mass of cyanocobalamin, assuming that there is one atom of cobalt in every molecule of cyanocobalamin. WebAssign will check your answer for the correct number of significant figures. g/mol
Answer:
645 g/mol
Explanation:
Step 1: Given data
Percent by mass of cobalt in cyanocobalamin: 4.34%
Step 2: Determine the molar mass of cyanocobalamin
There is one atom of cobalt in every molecule of cyanocobalamin, or what is the same, there is 1 mole of atoms of Co in every mole of molecules of cyanocobalamin. Given the molar mass of Co is 28.01 g/mol, the molar mass of cyanocobalamin is:
100 g B12/4.34 g Co × 28.01 g Co/1 mol Co × 1 mol Co/1 mol B12 = 645 g/mol
