What special label do you have to use when naming ionic compounds with transition metals?
A) Roman Numerals
B) Greek Numerals
Naming Ionic compounds with transition metals requires the use of a roman numeral. The charge of the metal ion must be written in the name of the compound with a roman numeral. This is because transition metals can have more than one valence (or charge).

Answer:
You can see that the line is going up and is curved in a positive direction.
Explanation:
When an object is speeding up, the acceleration is in the same direction as the velocity. Thus, this object has a positive acceleration.

Is carbon dioxide in the atmosphere beneficial or detrimental to the environment?
Answer:
Carbon dioxide is essential to the survival of plants and animals. Too much, however, can cause all life on Earth to die. Not only do plants and animals need to ingest carbon dioxide, but they also rely on the gas to keep them warm, as it is an essential component to Earth's atmosphere.
Answer:
Yes
Explanation
Carbon dioxide is essential to the survival of plants and animals. Too much, however, can cause all life on Earth to die. Not only do plants and animals need to ingest carbon dioxide, but they also rely on the gas to keep them warm, as it is an essential component to Earth's atmosphere.

What is Proteins Structure
Answer:
Protein structure is the three-dimensional arrangement of atoms in an amino acid-chain molecule. Proteins are polymers – specifically polypeptides – formed from sequences of amino acids, the monomers of the polymer. ... Protein structures range in size from tens to several thousand amino acids.
Oxygen difluoride is a hazardous, highly explosive gas used as a propellant. A sample of this compound weighing 0.432 grams is analyzed. It contains .128 grams of oxygen. What is the percentage composition of oxygen and fluorine in this compound ? (Show work)
Answer:
Percentage composition of oxygen = 29.69%
Percentage composition of fluorine = 70.37
Explanation:
Given:
Mass of compound = 0.432 grams
Mass of oxygen = 0.128 grams
Find:
Percentage composition of oxygen
Percentage composition of fluorine
Computation:
Percentage composition of oxygen = [0.128/0.432]100
Percentage composition of oxygen = 29.69%
Percentage composition of fluorine = [(0.432 - 0.128)/0.432]100
Percentage composition of fluorine = 70.37

Explanation:
A gas at 127 celsius and 10.0 L expands to 20.0 L. What is the new
temperature in kelvin? (You must convert to Kelvin before calculating
this problem
Answer:
T₂ = 800 K
Explanation:
Given that,
Initial temperature of the gas, T₁ = 127°C = 400 K
Initial volume, V₁ = 10 L
Final volume, V₂ = 20 L
We need to find the new temperature.
The volume of a gas is directly proportional to its Kelvin temperature.
Let T₂ is the new temperature. So,
[tex]\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}\\\\T_2=\dfrac{V_2T_1}{V_1}\\\\T_2=\dfrac{20\times 400}{10}\\\\T_2=800\ K[/tex]
So, the new temperature of the gas is 800 K.

How moles are in 45.7g of CH3?
first find the atomic weight of CH3 which would be
atomic weight: 12.011 (3×1.008) = 36.32 g/mol
then find the moles in the given mass
36.32 ÷ 45.7 = 0.794
I HOPE I'M NOT WRONG I HAVENT DONE CHEM IN SO LONG
Calculate the molarity for a solution containing 0.34 moles of NaNO3 dissolved in 0.5 liter of
water.
Answer:
0.68 mol/L
Explanation:
M=m/l
m is moles and l is liters
Since they gave us the values in the correct units, all we have to do it plug it in
M=0.34 mol/0.5 liters
M=0.68

A sample of gas in a closed container at a temperature of 100oC and 3 atm is heated to 300oC. What is the pressure of the gas at the higher temperature?
Answer:
6.14 atm
Explanation:
Initial temperature (T₁) = 100 °C
Initial pressure (P₁) = 4 atm
Final temperature (T₂) = 300 °C
Final pressure (P₂) =?
NOTE: Volume = constant (since the system is a closed system)
Next, we shall convert celsius temperature to Kelvin temperature. This can be obtained as follow:
T(K) = T(°C) + 273
Initial temperature (T₁) = 100 °C
Initial temperature (T₁) = 100 °C + 273 = 373 K
Final temperature (T₂) = 300 °C
Final temperature (T₂) = 300 °C + 273 = 573 K
Finally, we shall determine the pressure at the highest temperature as follow:
Initial temperature (T₁) = 373 K
Initial pressure (P₁) = 4 atm
Final temperature (T₂) = 573 K
Final pressure (P₂) =?
P₁ / T₁ = P₂ / T₂
4 / 373 = P₂ / 573
Cross multiply
373 × P₂ = 4 × 573
373 × P₂ = 2292
Divide both side by 373
P₂ = 2292 / 373
P₂ = 6.14 atm
Thus, the pressure at the highest temperature is 6.14 atm

Which best represents a physical change?
A. formation of a new substance
B. formation of a precipitate
C. condensation
D. bubbling
Answer:
The answer I would go with is A formation of a new substance.
Explanation:
This is because physical change includes changes of state. Some could be changing from a liquid to gas or solid to gas. B is not even an answer that should be considered because it doesn't fit into the category. C and D represents some of the examples of the process of physical change. Like boiling, bubbling, melting, or freezing. So the best would be A.

Answer:
C. A one (1) is assumed when there is no coefficient
Explanation:
The following chemical equation is given in the attachment:
2H2 + O2 → 2H2O
In this reaction, Hydrogen (H2) and oxygen (O2) gases are the reactants and they combine to form H2O, which is the product. It is necessary that, in accordance to the law of conservation of matter, the same number of atoms of each elements on the reactant side equates that on the product side. When this happens, the equation is said to be BALANCED.
However, to balance an equation, COEFFICIENTS are used. In this equation above, coefficients 2 is used in front of both H2 and H2O but no coefficient is used in front of O2. This is because 1 mole of oxygen is on the reactant and product side respectively. However, one is assumed when no coefficient is written i.e. O2 means 1 mole of oxygen molecule.
