What kind of chemical relation is shown 2H2 plus O2 equals 2H2O?
A balanced chemical reaction.
What does a chemical reaction show?
It shows the preservation of mass and of matter.
A chemist synthesizes tin iodide according to the chemical reaction shown below The chemist starts with 10.0 g of tin and excess iodine After the reaction 36.8 g of tin iodide are obtained.?
69.7
A chemist synthesizes tin iodide according to the chemical reaction shown below The chemist starts with 15.0 g of tin and excess iodine After the reaction 66.3 g of tin iodide are obtained What is?
Theoretical yield is the maximum amount of product that can be obtained from a given amount of reactants, assuming the reaction goes to completion and no side reactions occur. In this case, the theoretical yield of tin iodide can be calculated by using the balanced chemical equation and the molar masses of tin and iodine.
What evidence of a chemical reaction is shown in the photo?
lol what photo
The proportions of the reactants and products involved in a chemical reaction are shown by the what in the balanced equation describing the reaction?
The coefficients in a balanced chemical equation show the proportions of the reactants and products involved in a chemical reaction. Each coefficient represents the number of moles of each substance in the reaction.
The number that tells how many molecules of a particular substance take part in a chemical reaction is?
When writing a BALANCED Reaction equation , it is the extreme left number(Molar ratio) that indicates the number of molecules reacting. e.g. H2SO4 + 2KOH = K2SO4 + 2H2O The molar ratios are 1:2::1:2 We can re-write this equation as H2SO4 + KOH + KOH = K2SO4 + H2O + H2O As you can see the 'KOH' and the H2O ' are written out twice.. So in order to eliminate this repetition we place a coefficient ( molar ratio) to the left of the given molecule.
Is the products of the reaction shown in a balanced chemical equation?
. A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.
What type of reaction is shown below Sr(s) plus Cl2(l) SrCl2(s)?
This is a single replacement reaction where strontium (Sr) replaces chlorine (Cl) in the compound, forming strontium chloride (SrCl2).
What kind of chemical relation is shown 2H2 plus O2 equals 2H2O?
A balanced chemical reaction.
What law is shown by a balanced equation?
The law of conservation of mass is shown by a balanced chemical equation, which states that matter cannot be created or destroyed in a chemical reaction. This means that the number of atoms of each element must be the same on both sides of the equation.
Ask us anythingOctane (C8H18) is found in gasoline. It is burned for fuel in a combustion reaction. The unbalanced combustion reaction for octane is shown below. C8H18 plus O2 CO2 plus H2O plus heat W?
The balanced combustion reaction for octane would be: 2C8H18 + 25O2 → 16CO2 + 18H2O + heat
How many moles of silver nitrate are needed to completely react with 0.327 mole of sodium cloride?
The balanced chemical equation for the reaction between silver nitrate (AgNO3) and sodium chloride (NaCl) is 2AgNO3 + 2NaCl → 2AgCl + 2NaNO3. Since the mole ratio between silver nitrate and sodium chloride is 2:2, 0.327 mole of sodium chloride would react with 0.327 moles of silver nitrate.
What is the balanced form of the chemical equation shown below Cr(s) plus Cl2(g) CrCl3(s)?
The balanced equation is: 2Cr(s) + 3Cl2(g) → 2CrCl3(s)
What is a numerial coefficient if the only number is a letter squared?
1 is the numerical coefficient if no other numeral is shown.
The reaction of hydrogen with nitrogen to produce ammonia is shown below. If there are 3 moles of nitrogen how many moles of hydrogen are needed to react completely with the nitrogen?
The balanced equation for the reaction is: 3H2 + N2 -> 2NH3 From the balanced equation, we can see that 3 moles of hydrogen are needed to react completely with 1 mole of nitrogen. So if there are 3 moles of nitrogen, you would need 9 moles of hydrogen to react completely.
What is conserved in the reaction shown below. N g plus 3F g 2NF g?
In this reaction, the total number of atoms of each element remains the same before and after the reaction. This is due to the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction.
