____ NaF + ____ Br2 à ____ NaBr + ____ F2
A. ---, 2, 2, ---
B. 2, ---, ---, 2
C. 2, ---, 2, ---
Answer:
2 NaF + Br2 --> 2NaBr + F2
Explanation:
Well first I notice that there are two flourines on the products side so we need to put a 2 of NaF. Now there are 2 sodiums on the products side so we have to put another two in front of NaBr.
2 NaF + Br2 --> 2NaBr + F2

what is the other term used to describe tropical cyclone when it is formed in the northwestern part of the pacific ocean
Answer:
Typhoons
Explanation:
A tropical cyclone is a word that is used by meteorologists to explain a rotating, organized system of clouds & thunderstorms that take their origins over tropical or subtropical waters and also possess closed but low-level circulation.
Now, In the Northwest part of the Pacific ocean, these tropical cyclones which are west of the dateline are referred to as Typhoons while In the southwest Pacific and in the Indian Ocean they are called Cyclones. Lastly, those that form over the Atlantic Ocean or eastern Pacific Ocean are referred to as hurricanes
3. How many atoms are in 85 moles H2O?
Answer:
5.119 *10^25
Explanation:
1 mole = 6.022 * 10^23
[tex]\frac{85 mol H20}{1} =\frac{6.022*10^2^3}{1 mol H20}[/tex]
the moles cancel out so you get
85 * (6.022*10^23)
Plug that into the calculator so you get:
5.119 *10^25
Beryllium

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

A gas at a pressure of 360 torrs and a volume of 750 ml. If the pressure becomes 1.5 atm what is the new volume?
Answer:
V₂ = 236.84 mL
Explanation:
The relation between pressure and volume is inverse.
We can write it as follows :
[tex]P_1V_1=P_2V_2[/tex]
We have,
P₁ = 360 torrs, V₁ = 750 mL, P₂ = 1.5 atm = 1140 torr.
So,
[tex]V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{360\times 750}{1140}\\\\V_2=236.84\ mL[/tex]
So, the new volume of the gas is 236.84 mL.
¿Cuántos moles de bióxido de Nitrógeno (NO 2) se forman cuando reaccionan 5 moles de Nitrógeno (N 2)?
Answer:
10 moles de NO2
Explanation:
Tenemos la ecuación de la reacción como sigue;
N2 (g) + 2 O2 (g) → 2 NO2 (g)
Asi que;
Si 1 mol de nitrógeno produce 2 moles de NO2
5 moles de nitrógeno producirán 5 * 2/1 = 10
Por tanto, se producen 10 moles de NO2 moles

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).
