Help please with the 2 questions i will mark you brainliest
Answer:
The first one would be "Both Mixtures and Compounds", while the second one would be "Solution 2 - Because she used more salt".
Explanation:
An element is made up of atoms, but to make a mixture or compound you are combining multiple elements. And when look at the second question, assuming they have the same amount of water, there is a higher ratio of salt in the second one, which would make it more concentrated.

explain ocean acidification
Answer:
Ocean acidification refers to a reduction in the pH of the ocean over an extended period of time, caused primarily by uptake of carbon dioxide (CO2) from the atmosphere
Explanation:
Answer:
Ocean acidification affects marine life
Acidification reduces the availability of carbonate ions in ocean water, which provide the building blocks these organisms need to make their shells and skeletons, significantly reducing the chances for their offspring to survive.
Explanation:
Ocean acidification is the ongoing decrease in the pH of the Earth's oceans, caused by the uptake of carbon dioxide (CO. 2) from the atmosphere. The main cause of ocean acidification is the burning of fossil fuels.

Answer:
1. Acids
2. Its molecular arrangement
3. Very acidic
4. Unsaturated
5. Apple juice
Explanation:
1. Acids have pH less than 7
2. Water molecules have a polar arrangement of the oxygen and hydrogen atoms—one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge.3. Very acidic
4. Unsaturated solutions are solutions in which the amount of dissolved solute is less than the saturation point of the solvent (at that specific temperature gradient).
5. The lower the pH, the more hydrogen molecules.

What does MVLMEN stand for
How many moles of glucose are produced?
How many moles of oxygen are produced?
Explanation:
5.00 mol H2O × (1 mol C6H12O6/6 mol H2O)
= 0.833 mol C6H12O6
5.00 mol H2O × (6 mol O2/6 mol H2O)
= 5.00 mol O2

Explanation:
A nucleus of uranium 235 decays. Its decay produces a nucleus of an unknown element (x), a nucleus of helium 4 and energy. What kind of radiation is produced by this decay?
Gamma beta or alpha?
Answer: Alpha
Explanation:
Alpha particle form of decay produces a nucleus similar to the element helium. During Alpha decay an atom spits out two protons and two neutrons from its nucleus.
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
In a chemical reaction, mass is conserved. This means that...
O A. The mass of the reactants stays the same during a chemical reaction
OB. The mass of the products stays the same during a chemical reaction
OC. The tpye and number of atoms in the reactants equals the type and number of atoms in the products
OD. The mass of the products is always twice the mass of the reactants
Answer: D
Explanation:
How many moles is 45g of KCl?
Answer:
60.36
Explanation:
Answer: 0,60 mol
Explanation:
Molar mass of KCl is M = (39.10 + 35.45) g/mol = 74,55 g/mol
amount of substance n = m/M = 45 g / 74.55 g/mol

Si 4 L de un gas están a 0,79 atm de presión, ¿Cuál será su nuevo volumen, si aumentamos la presión hasta 1,05 atm?
Respuesta:
3 L
Explicación:
Paso 1: Información provista
Volumen inicial del gas (V₁): 4 LPresión inicial del gas (P₁): 0,79 atmVolumen final del gas (V₂): ?Presión final del gas (P₂): 1,05 atmPaso 2: Calcular el volumen final del gas
Si suponemos que el gas se comporta como un gas ideal y que la temperatura permanece constante, podemos calcular el volumen final del gas usando la ley de Boyle.
P₁ × V₁ = P₂ × V₂
V₂ = P₁ × V₁ / P₂
V₂ = 0,79 atm × 4 L / 1,05 atm = 3 L

Se disuelven 10 g de acido carbónico H2CO3 en 150 g de agua. Determina la concentración % m/m de esa disolución?
The question is: 10 g of carbonic acid H2CO3 are dissolved in 150 g of water. Determine the% m / m concentration of that solution?
Answer: The% m / m concentration of that solution is 6.66%.
Explanation:
Given: Mass of solute = 10 g
Mass of solvent = 150 g
Formula used to calculate the %m/m is as follows.
[tex]Percent (m/m) = \frac{mass of solute}{mass of solvent} \times 100[/tex]
Substitute the values into above formula as follows.
[tex]Percent (m/m) = \frac{mass of solute}{mass of solvent} \times 100\\= \frac{10 g}{150 g} \times 100\\= 6.66%[/tex]
Thus, we can conclude that the% m / m concentration of that solution is 6.66%.
