Answer:
A. Interpersonal racism
Explanation:
Its not stereotypical to think that an Asian cant speak Spanish. The fact that he thought, Asian-sounding name, is stereotypical on its own, but taking in this entire situation, this is not racial stereotyping. It's also not racial inequality, since Ty isn't saying that Asians are asian people are lesser than another group. Institutional racism occurs when schools, governments, etc etc that seem race neutral are actually disadvantage racially marginalized groups and privilege whites.

what type of chemical reaction is it?
Answer:
Complete ionic equation
Explanation:
For every reaction, we could write the molecular equation as well as the ionic equation. The net ionic equation only shows the reaction of the main ions that take part in the reaction. It does not show the reaction of spectator ions.
In order to write the complete ionic equation for any reaction, we must observe the following steps;
We have to start by writing a balanced molecular equation for that particular reaction. Secondly, we split up the soluble strong electrolytes solutions into their constituent ions. It is necessary to indicate the correct formula and charge for each ion participating in the reaction. The individual stoichiometric coefficients of each ion is used toindicate the correct number of all the participating ions. All compounds formed during the reaction are noted with the appropriate symbols (s) for solid, (l) for liquid, or (g) for gaseous respectively.

How many ml of solution are needed to make a 5.78 M solution with 2.98 moles of CaO?
Answer:
515.6 mL
Explanation:
Please see the step-by-step solution in the picture attached below.
Hope this answer can help you. Have a nice day!
The number of mL of the solution needed to make a 5.78 M solution with 2.98 moles of CaO is 516 mL.
The number of moles that is present in a liter of solution is regarded to be the Molarity of the solution that is measured in mol/L.
[tex]\mathbf{Molarity = \dfrac{number\ of \ moles(n)}{Volume \ (in \ liters)}}[/tex]
[tex]\mathbf{Molarity = \dfrac{2.98 moles }{5.78 \ mol/ L}}[/tex]
Molarity = 0.51557 L
If 1 Liter of solution contains 1000 mL, then 0.51557 L will contain:
= 0.516 × 1000 mL
= 516 mL of solution.
Therefore, we can conclude that the number of mL of the solution needed to make a 5.78 M solution with 2.98 moles of CaO is 516 mL.

5. Do you think oppositional or symbiotic relationships are more beneficial to an ecosystem? Justify
your answer.
Answer:
I think they are beneficial for the life of those symbiotic organisms that require yes or yes from another to be able to live.
Although an ecosystem could not be carried out if only this relationship would occur, since symbiotic relationships we have an organism where it needs another to live and even removes the necessary nutrients for it, that is why the chain should continue with other types of relationships .
Explanation:
The symbiosis is defined as "Intimate association of organisms of different species to mutually benefit in their vital development" that is why adequate coexistence between these living organisms is needed, otherwise this phenomenon would not occur.
A very good example of the symbiosis is: Bees and plants where the bee is the pollinating agent of the plant so that it continues to reproduce and the plant is the bee's food source.
Therefore I believe that the development of this type of relationship is VITAL, and very fundamental, otherwise I do not know if an ecosystem or a balanced ecosystem could be carried out.

Earth's gravity. How will this be possible?
Simulating Earth's gravity in space would be challenging, but it is possible to create artificial gravity using centrifugal force. Centrifugal force is the outward force experienced by an object that is moving in a circle.
What is gravity?An unobservable force that draws things together. Anyone remains on the ground thanks to Earth's gravity, which also causes objects to fall.
One way to create artificial gravity in space is by building a rotating space station. The station would consist of two main parts: a central hub and a rotating section.
The hub would contain the crew quarters, life support systems, and other essential components, while the rotating section would be attached to the hub via a set of cables or other structures.
The rotating section would be set spinning, creating centrifugal force that would push the crew towards the outer rim of the section. This force would create a sensation of gravity that would be similar to that experienced on Earth.
Thus, by rotating a spacecraft, it is possible to create a centrifugal force that mimics the gravitational force of Earth.

how many grams of oxygen are produced if 25.0g of potassium chlorate decomposes according to the reaction 2KCLO3 —-> 2KCL +3O2
Answer:
approximately 15.1 grams.
Explanation:
The key to chemistry is to change everything to moles. Then when you have the answer in moles change the answer back to grams, liters, or whatever you want.
change 25 grams of potassium chlorate to moles.
calculate the gram molecular mass of potassium chlorate.
Chlorate is Cl with 3 oxygens. ate = saturated. Chlorine has seven valance electrons when it is saturated six of these electrons are used by oxygen ( 2 electrons per oxygen) leaving only 1 electron.
1 K x 39 grams/mole
+1 Cl x 35.4 grams/ mole
+3 O x 16 grams/ mole
= 122.4 grams / mole Potassium Chlorate
25
122.4
= moles.
2.05 moles of Potassium Chlorate.
There is a 1:1 mole ratio. 1 mole of Potassium Chlorate will produce 1 mole of Potassium Chloride.
2.05 moles of Potassium Chlorate will produce 2.05 moles of Potassium Chloride.
Find the gram molecular mass of Potassium Chloride.
1 K x 39 = 39
+1 Cl x 35.4 = 35.4
= 74.4 grams / mole.
2.05 moles x 74.4 grams/ mole = 15.2 grams

Answer:
9.79g of O2
Explanation:
So this question you are trying to go from g of KCLO3 to grams of oxygen. There is no direct conversion so you have to utilize multiple process.
[tex]25.0g KCLO3 * \frac{1mol KCLO3}{122.55 gKCLO3} * \frac{3mol O2}{2 mol KCLO3} * \frac{32.00g O2}{1mol O2}[/tex]
=9.79 g of O2
So first you go from g of KCLO3 to moles of KCLO3 by using molar mass of KCLO3. Then you use mol:mol ratio from balanced equation to go to moles of O2, and finally use molar mass of O2 to go to grams of O2.
Which ion H₃O⁺ or OH⁻, is in greater concentration?
Answer:
The OH- ion concentration is greater than the H3O+ ion concentration.
Explanation:
Balance the following reaction CS2+Cl2. CCl4+S2Cl2
Answer:
CS₂ + 3Cl₂ ⇒ CCl₄ + S₂Cl₂
Explanation:
This one is relatively simple. When we take inventory of both sides, we see 1 Carbon, 2 Sulfurs, and 2 Chlorines on the reactant side, and 1 Carbon, 2 Sulfurs, and 6 Chlorines on the product side. Since we have Cl₂ on the left and we want 6 on the left, let's add a coefficient of 3 to Cl₂. This balances everything out! Final answer: CS₂ + 3Cl₂ ⇒ CCl₄ + S₂Cl₂. Hope this helps!

1. A solution was made by dissolving 0.837g of Ba(OH)2 in 100 mL of solution. What is the pOH and pH of the solution?
2. What is the percentage ionization of 1.0M acetic acid? What is the pH of this solution?
Answer:
1. pOH = 1.01 and the pH = 12.99.
2. a) %I = 0.417 %, b) pH = 2.34.
Explanation:
1. The pH of the dissolution of Ba(OH)₂ in water can be calculated using the following equation:
[tex]pH = 14 - pOH = 14 - (-log[OH^{-}]) = 14 + log[OH^{-}][/tex]
To find the pOH, first, we need to calculate the concentration (C) of Ba(OH)₂:
[tex] C_{Ba(OH)_{2}} = \frac{\eta}{V} = \frac{m}{M*V} [/tex]
Where:
η: is the number of moles of Ba(OH)₂
V: is the volume of the solution = 100 ml = 0.100 L
M: is the molar mass of Ba(OH)₂ = 171.34 g/mol
m: is the mass of Ba(OH)₂ = 0.837 g
[tex] C_{Ba(OH)_{2}} = \frac{m}{M*V} = \frac{0.837 g}{171.34 g/mol*0.100 L} = 0.049 mol/L [/tex]
Knowing that in 1 mol of Ba(OH)₂ we have two moles of OH⁻, the concentration of OH⁻ is:
[tex] C_{OH^{-}} = \frac{2*\eta_{Ba(OH)_{2}}}{V} = 2*C_{Ba(OH)_{2}} = 2*0.049 mol/L = 0.098 mol/L [/tex]
Now, we can find the pOH and the pH of the solution:
[tex] pOH = -log[OH^{-}] = -log(0.098) = 1.01 [/tex]
[tex] pH = 14 - pOH = 14 - 1.01 = 12.99 [/tex]
2. a) The percentage of ionization (% I) of acetic acid can be calculated using the following equation:
[tex]\% I = \frac{[H^{+}]_{eq}}{[HA]_{0}}*100[/tex]
We need to find the [H⁺] = [H₃O⁺] at the equilibrium:
CH₃COOH(aq) + H₂O(l) → CH₃COO⁻(aq) + H₃O⁺(aq)
1.0 - x x x
[tex] Ka = \frac{[CH_{3}COO^{-}]*[H_{3}O^{+}]}{[CH_{3}COOH]} [/tex]
Ka: is the dissociation constant of acetic acid = 1.75x10⁻⁵
[tex] 1.75\cdot 10^{-5} = \frac{x^{2}}{1.0 - x} [/tex]
[tex] 1.75\cdot 10^{-5}(1.0 - x) - x^{2} = 0 [/tex] (1)
By solving equation (1) for x we have two solutions:
x₁ = -0.00417
x₂ = 0.00417 = [H₃O⁺] = [CH₃COO⁻]
We will take the positive value to find the percentage ionization:
[tex]\% I = \frac{[H^{+}]_{eq}}{[HA]_{0}}*100 = \frac{0.00417 M}{1.0 M}*100 = 0.417 \%[/tex]
b) The pH of the solution is:
[tex] pH = -log([H_{3}O^{+}]) = -log(0.00417) = 2.34 [/tex]
I hope it helps you!
