when hydrogen and oxygen combine then they form water as product
also in neutralization reaction water form as product
hope it helps
Water is always a product in a type of chemical reaction called a neutralization reaction.
A reaction is a process that involves the transformation of one or more substances into one or more different substances.
Neutralization reaction is type of reaction occurs when an acid and a base react together to form a salt and water. The general equation for a neutralization reaction is:
[tex]\rm acid + base \rightarrow salt + water[/tex]
In this type of reaction, the hydrogen ions ([tex]\rm H^+[/tex]) from the acid combine with the hydroxide ions ([tex]\rm OH^-[/tex]) from the base to form water ([tex]\rm H_2O[/tex]). The remaining ions from the acid and the base combine to form a salt.
Therefore, water is always a product in a neutralization reaction, which occurs when an acid and a base react together to form a salt and water.

what is the volume, in liters, of 5.500 mol of C3H3 gas at STP
Answer:
123.2 Liters.
Explanation:
At STP (T = 273K & P = 1atm), one mol of any gas will occupy 22.4 liters.
With the above information in mind, we can calculate how many liters would 5.500 mol of gas occupy:
5.500 mol * 22.4 L / mol = 123.2 L
So 5.500 moles of C₃H₃ would have a volume of 123.2 liters at STP.

An experiment requires 66.6 g of ethyl alcohol (density = 0.790 g/mL). What is the volume?
Answer:
Volume = 84.30 mLExplanation:
Mass = 66.6 gram
Density = 0.790 g/mL
Volume = Mass ÷ Density
Volume = 66.6 ÷ 0.790
Volume = 84.30 mL

Answer:
750 mmHg
Explanation:
From the question given above, the following data were obtained:
Partial pressure of CO₂ (Pₐ) = 250 mmHg
Partial pressure of N₂ (P₆) = 375 mmHg
Partial pressure of He (P꜀) = 125 mmHg
Pressure of the mixture (Pₜ) =?
The pressure of the mixture of the gases can be obtained as follow:
Pₜ = Pₐ + P₆ + P꜀
Pₜ = 250 + 375 + 125
Pₜ = 750 mmHg
Therefore, the pressure of the mixture of the gases is 750 mmHg
what explains the bonding in a compound made from carbon and hydrogen
1) ch4 because every hydrogen gets two electrons to bond
2) ch4 because 8 electrons are shared in this molecule
Answer:
2) ch4 because 8 electrons are shared in this molecule
Explanation:
The bond between carbon and hydrogen in the molecule; CH4 is a covalent bond. This bond involves sharing of electrons. Carbon has a valency of 4 and needs four more electrons to complete it's electronic configuration. These 4 electrons are taken care of by the 4 hydrogen atoms which each have a valency of 1.

A student performed a similar experiment we have done, with Ag and O to produce silver oxide.
Mass of crucible and lid: 29.307 g
Mass of crucible, lid, and silver: 30.958 g
Mass of crucible, lid, and silver oxide: 31.080 g
Use the above data to calculate the moles of the metal used in this experiment. your answer must include correct significant figures and unit.
Answer:
0.0153 mol
Explanation:
Mass of crucible and lid: 29.307 g
Mass of crucible, lid, and silver: 30.958 g
Number of moles = Mass /Molar mass
Mass of Silver = Mass of crucible, lid, and silver - Mass of crucible and lid
Mass of siilver = 30.958 g - 29.307 g
Mass of silver = 1.651 g
Molar mass of silver = 107.868 g/mol
Number of moles = 1.651 g / 107.868 g/mol
Number of moles = 0.0153 mol

Convert 1.55 x 10^24 ATOMS OF CARBON TO MOLES OF CARBON
Answer:
2.57 moles of carbon
Explanation:
1 mole = 6.023x10^23 (this is called avogadro's number)
1/6.023x10^23
1.55x10^24 = 1.55x10^24/6.023x10^23 = 2.57 moles
this means, 1.55x10^24 atom contains 2.57 moles of carbon

What's the mass in grams of 0.334 moles of sucrose (C12H22O11)?
Answer:
114.23g
Explanation:
Mass = xg
Mole = 0.334 mol
Molar mass of Sucrose
(C = 12, H = 1, O = 16)
C12H22O11
(12×12)+(1×22)+(16×11)
144 + 22 + 176
342g/mol
Mass = No of mole × Molar mass
Mass = 0.334 × 342
Mass = 114.228
Mass ≈ 114.23g

Air in a closed cylinder is heated from 15°C to 36°C. If the initial pressure is 1000 torr, determine what is the final pressure? *
Answer:
1072 torr
Explanation:
To answer this problem we can use Gay-Lussac's law, which states:
P₁T₂=P₂T₁Now we convert the given temperatures into K:
T₁ = 15°C ⇒ 15+273.16 = 288.16 KT₂ = 36°C ⇒ 36+273.16 = 309.16 KWe input the data:
1000 torr * 309.16 K = P₂ * 288.16 KAnd solve for P₂:
P₂ = 1072 torrsupposing on a hypothetical garden 43 identical trees contains a total of 19565 leaves. if each branch on a given tree consist of 35 leaves how many branches does each tree have?
Answer:
13 branches/tree
Explanation:
Step 1: Given data
Total number of trees (t): 43 treesTotal number of leaves (l): 19565 leavesNumber of leaves per branch (l/b): 35 leaves/branchStep 2: Calculate the total number of branches (b)
We will use the following expression.
b = l × b/l
b = 19565 leaves × 1 branch/35 leaves = 559 branch
Step 3: Calculate the number of branches per tree (b/t)
We will divide the total number of branches by the total number of trees.
559 branches/43 trees = 13 branches/tree

what mass of sodium hydroxide is needed to neutralise 24.5kg of sulfuric acid
H2SO4 + N2 = 2NH3
Answer:
23.92 g
Explanation:
Molar mass of H2SO4 = (2×1)+32+(16×4)= 2+32+48= 82g/mol
H2SO4 + 2NaOH ---> Na2SO4 + 2H2O
I mole of H2SO4 = 2 moles of NaOH
24.5/82 = 24.5/82 × 2
= 0.598 moles of NaOH will neutralize
Mass= mole× molar mass
Molar mass of NaOH= 23+16+1 = 40g/mol
Mass= 0.598 × 40 = 23.92g of NaOH
Answer:
20g
Explanation:
First of all, you have got your formula wrong. It should be [tex]H_{2}SO_{4} + 2NaOH = Na_{2}SO_{4} + 2H_{2}O[/tex].
Start by finding the Relative Formula Mass for sulfuric acid. [tex]H_{2}SO_{4}[/tex] is equal to (2x1)+32+(16x4)=98. You then calculate Mols by doing [tex]Mols=\frac{Mass}{Relative Formula Mass}[/tex]. So, [tex]\frac{24.5}{98} = 0.25[/tex], so the Mols of Sulfuric Acid is 0.25.
The Mol ratio of Sulfuric Acid to Sodium Hydroxide is 1:2, so 0.25:0.5.
Now, you have to find the Relative Formula Mass of Sodium Hydroxide, or [tex]NaOH[/tex]. 23+16+1=40. Finally, multiply 0.5 by 40, and you'll find that the maximum mass is 20g.

Answer:
A. Bees bringing pollen from the flower of one plant to the flower of another plant.
Explanation:
Genetic diversity in organisms is enhanced by the process of sexual reproduction due to the meiotic process that the participant organisms undergo to produce gametes. A process unique to meiosis called CROSSING OVER ensures that the alleles of genes are recombined in the GAMETE or sex cells.
According to this question, POLLINATION, which is the transfer of pollen from a male flower to a female one, will lead to sexual reproduction via fertilization. However, a cross-pollination, which requires a pollinator like the bees in this question will ensure the most genetic diversity among the offsprings.
