-Water levels are dangerously high for wildlife and humans.
-Animals seem to be lost, like the cow and the sheep especially.
2.
-There are not many trees near the water, meaning less areas for wildlife to live.
-There is not much wildlife in general.
Inferences
1. The wildlife shown will move relocate and adapt to another area.
2. Industry — emissions are visible in top left— will continue to hurt the environment. CO2 emissions will increase.

What do we know about the arrangement of atoms during a chemical reaction?
Answers
Answer: In a chemical reaction, the atoms and molecules that interact with each other are called reactants. ... No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

the following punnett square shows a cross between two hybrid flowers. if the flowers show incomplete dominance, what fraction are pure red? I NEED HELP PLZ!
Answers
Answer:
1/4
Explanation:
Incomplete dominance is when the dominant ("R") gene is not completely dominant and cannot fully mask or cover the recessive ("r") gene. This means that it will result in both genes expressing and a mix of traits appearing. In the case of a flower with "R" genes for red and "r" genes for white, the following possibly combinations exist:
RR = all red, no white "r" gene
Rr = pink, as both the "R" and "r" genes are expressed
rr = white, no red "R" gene
The Punnett Square shows that only one of the four phenotypes is RR and red.

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.
how much heat is needed to warm 250g of water from 22°C to 98°C ?
Answers
Answer:
79'420J
Explanation:
We know mass 250g and
∆T=98°C -22°C
=76°C
The specific heat capacity for water is 4,18Zj/g°C
THEREFORE
∆H=250g•14,8j/g°C •76°C
=79'420J
How many grams are there in 9.03 x 1023 molecules of CO2?
Answers
Answer:
The correct answer is - 66g.
Explanation:
Given:
molecules of CO2 = 9.03 x 10^23
We know:
1 mole of any substance = 6.02x10^23 molecules. (Avogadro's number)
M (CO2) = 12 + (2x16) = 12 + 32 = 44g
Solution:
The mass of CO2 with 9.03x10^23 molecules would be:
44g of CO2 = 6.02x10^23 molecules.
So, the mass in grams of CO2 (X) = 9.03x10^23 molecules
Xg of CO2 = (44x9.03x10^23)/6.02x10^23 = 66g
Thus, the correct answer would be - 66gm.

Answers
Answer: it’s not A3X3
Explanation:
1. AX
For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion.If a cation A carries +3 charge and an anion X carries -3 charge, the compound so formed is AX. Since the charges gets cancelled out.For example: consider aluminum phosphate, aluminum carries +3 charge and phosphate carries -3 charge, the molecular formula for the compound will be AlPO₄.Learn more:

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?
Answers
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
What is the limiting reactant if 10 moles of NH 3 react with 30.0 moles of NO ?

What effect does the concentration of reactants have on the rate of a
reaction?
A. Changing the concentration has no effect on the reaction rate.
B. Increasing the concentration decreases the rate of the reaction.
O C. Increasing the concentration increases the rate of the reaction.
O D. The effect of concentration on rate varies within the reaction.
Answers
Answer:
C
Explanation:
The answer is C as concentration is a major factor affecting the rate of reaction and it has a direct relationship with the rate of reaction.
The effect that the concentration of reactants has on the rate of a reaction is increasing the concentration increases the rate of the reaction. The correct option is C.
What is a reactant?A reactant is a part of a reaction that is the first part of the reaction. Reactant can be more than one in the reaction. The different reactant reacts, and form a totally different product.
H2 + O2 = H2O
The hydrogen and oxygen are the reactants of the reaction.
Thus, the correct option is C. Increasing the concentration increases the rate of the reaction, as concentration plays a significant role in determining the rate of reaction and is directly related to it.

Answer:
Visit: gotit-pro.com
Explanation:
119 kPa x 1 atm/101 kPa = 1.18 atm
2) Convert temperature to Kelvin
35 + 273 = 308 K
3) Use PV=nRT and solve for V
(1.18 atm)(V)=(0.0972 mol)(0.0821)(308 K)
V = (0.0972 mol)(0.0821)(308 K) / (1.18 atm)
V = 2.08 L

Answers
Answer:
7.67
Explanation:
According to molar concentration, the molarity of solution which contains 22.41 grams of NaCl in 50.0 ml of solution is 7.67 M.
What is molar concentration?Molar concentration is defined as a measure by which concentration of chemical substances present in a solution are determined. It is defined in particular reference to solute concentration in a solution . Most commonly used unit for molar concentration is moles/liter.
The molar concentration depends on change in volume of the solution which is mainly due to thermal expansion. Molar concentration is calculated by the formula, molar concentration=mass/ molar mass ×1/volume of solution in liters.
In terms of moles, it's formula is given as molar concentration= number of moles /volume of solution in liters.Substitution of values in the given formula gives, molarity= 22.41/58.44×1/0.05=7.67 M.
Thus, the molarity of solution which contains 22.41 grams of NaCl in 50.0 ml of solution is 7.67 M.
