How to convert mole to grams?Calculate the number of moles mentioned in the questionFind the molar mass of the substance.Multiply both the values.3 KOH + H3PO4 → K3PO4 + 3 H2O
Step 1: Convert from grams to moles using the molar mass.
Step 2: Use the molar ratio to determine moles of other substance.
Step 3: Convert from mole to grams using the molar mass.
Convert grams to moles using the molar mass
25.4g KOH (1 mol KOH/56.098g KOH)
= 0.3593mol KOH
Mass of H3PO4 produced
0.3593 mol KOH ( 1 mol H3PO4/3 mol KOH)
= 0.1197 mol H3PO4
converting mole to grams
0.1197 mol H3PO4 (98g H3PO4/1 mol H3PO4)
= 11.730g H3PO4
Mass of K3PO4 produced
0.3593 mol KOH (1 mol K3PO4/3 mol KOH)
= 0.1197 mol K3PO4
converting mole to grams
0.1197 mol K3PO4 (212.267g K3PO4/1 MOL K3PO4)
= 25.408g K3PO4
Hence, option b is the correct answer.

Which kind of worm has a closed circulatory system?
a planarian
a fluke
a pinworm
an earthworm
An earthworm has a closed circulatory system.
The earthworm has a closed circulatory system. An earthworm circulates blood exclusively through vessels. There are three main vessels that supply the blood to organs within the earthworm.
As important as they are alive for distributing nutrients and organisms and decomposing matter, worms are also very important in the food chain. They provide a crucial protein-rich source of food for other important species like birds, hedgehogs and frogs.
They may live up to eight years, though one to two is more likely. Full size for an earthworm varies among species, ranging from less than half an inch long to nearly 10 feet.

D
E
Heres another for you guys!
Answer:
I believe it is E because the battery has a wire, a power source(the battery), and a bulb connected together thus making a full series circuit. Furthermore, the more batteries they are to a series circuit, the more dimmer the light bulbs will be.
5) Chlorine has 7 valence electrons. Neon has 8 valence electrons. Which on is more likely to undergo a
chemical reaction, and why?
Answer:
well, chlorine will undergo in a chemical reaction
Explanation:
neon has completed valence shells, so it neither need electron and or it also don't need to donate the electrons. hence it will not participate in any chemical reaction and it is stable in nature.
whereas chlorine need one more electron to complete it's valence shell and in order to be stable , so it will try to gain one electron , hence
it will take place in a chemical reaction

The Princess cruise ship left San Francisco and traveled south for 8 hours at a speed of 30mph. What is the velocity of the ship? Round your answer to the hundreths place
Answer:
v = 300 mph due South.
Explanation:
Given that,
The Princess cruise ship left San Francisco and traveled south for 8 hours at a speed of 30mph.
We need to find the velocity of the ship. It can be calculated by total distance divided by total time taken.
Velocity is a vector quantity i.e. it has both magnitude and direction. On the other hand, the speed has only magnitude (scalar quantity).
In this case it is mentioned that the cruise is travelling south with a speed of 300 mph.
Hence, the velocity is 300 mph in South direction.
Carlita’s body is made up of many cells. What is one thing all her cells have in common?
Answer:
All of them have a nucleus..
Explanation:
Pretty simple stuff. There's no cell without one.
Carlita’s body is made up of many cells. The one thing that all her cells have in common is they have the same kind of genes.
What are genes?Genes are tiny pieces of spherical hereditary material that are bead-shaped and found on chromosomes. They hold the organism's genetic makeup. The number of genes on each chromosome is incalculable.
The hereditary material that makes up chromosomes is arranged in x shapes inside the nucleus. DNA, genes, and proteins make it up. An organism's genotype is distinct from other organisms because of its distinct genetic makeup, and this distinction can be passed down from one generation to the next.
Traits may be influenced by genes, the environment, or a mixture of the two. Quantitative features can also be qualitative, such as eye colour (such as height or blood pressure).
Therefore, numerous cells make up Carlita's body. Her cells all share the same type of genes, which is the only thing that unites them.

(AKS 2e) Group 2 metals bond with nonmetals or polyatomic ions. What question
would a student need to know to form a compound with Group 2 metals? (DOK 2)
Will group 2 elements lose electrons to bond with nonmetals in group 17 in a
1:2 ratio?
Will group 2 elements lose electrons to bond with nonmetals in group 16 in a
2:1 ratio?
Will group 2 elements gain electrons to bond with nonmetals in group 17 in a
1:2 ratio?
Will group 2 elements gain electrons to bond with nonmetals in group 16 in a
2:1 ratio?
Answer:
Will group 2 elements lose electrons to bond with nonmetals in group 17 in a
1:2 ratio?
Explanation:
Metals are electropositive in nature. This means that they loose electrons. Thus, metals form ionic bonds by loosing electrons to non metals.
Elements of group 2 have a valency of 2 while those of group 17 has a valency of 1 so the ratio in which group 2 elements bond with elements of group 17 is 1:2. Hence the answer.

Someone please answer this...
Answer:
5446.8 J
Explanation:
From the question given above, the following data were obtained:
Mass (M) = 50 g
Initial temperature (T₁) = 70 °C
Final temperature (T₂) = 192.4 °C
Specific heat capacity (C) = 0.89 J/gºC
Heat (Q) required =?
Next, we shall determine the change in the temperature. This can be obtained as follow:
Initial temperature (T₁) = 70 °C
Final temperature (T₂) = 192.4 °C
Change in temperature (ΔT) =?
ΔT = T₂ – T₁
ΔT = 192.4 – 70
ΔT = 122.4 °C
Finally, we shall determine the heat required to heat up the block of aluminum as follow:
Mass (M) = 50 g
Specific heat capacity (C) = 0.89 J/gºC
Change in temperature (ΔT) = 122.4 °C
Heat (Q) required =?
Q = MCΔT
Q = 50 × 0.89 × 122.4
Q = 5446.8 J
Thus, the heat required to heat up the block of aluminum is 5446.8 J
