Answer:
E
Explanation:
A combination reaction is one in which two elements or two compounds react to give a new single compound
Hence, what we are expecting on the reactant side is only a single product and not a mixture of products
For the first reaction, we had two elements giving a single product
For the second reaction, we had same
For the third, we had same
For the fourth, we had two compounds reacting to give a singe new product
While in the last, we had two different products which means it does not follow the definition of a combination reaction and that makes it our answer
Answer: check for a change in total mass during a reaction.
According to the law of conservation of mass during a chemical change the total mass of the products remains equal to the total mass of the reactants: there is not change in the total mass.
During nuclear reactions the mass can change due to the huge release of energy which proceeds from mass change, as per the famous equation ΔE =Δm. c^2.
A and D
They are sometimes proven wrong and contradicted, so these would make the most sense
Answer: The solution to the problem expressed to he correct number of significant figures is 1.69
Explanation:
Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.
The rule applied for multiplication and division is :
The least precise number determines the number of significant figures in the answer.
As 12.0 has 3 significant digits and 7.11 also has 3 significant digits, the answer would also contain 3 significant digits.
For 
Thus the solution to the problem expressed to he correct number of significant figures is 1.69
Answer:
The pricing strategy is an important element in setting up the selling price of a product.
Explanation:
The pricing strategy is an important consideration while fixing up the selling price of product manufactured. When setting up a selling price of a product, the companies set up product calculation. Businesses should decide the pricing strategy before they advertise the products to the customers.
There are mainly 5 benefits to the businesses while doing a product calculation. They are:
--- Doing competition based pricing enables the company to compete with the rival companies product and is based on the market based study. Competition pricing is a useful tool for the retailers as well as the small businesses.
--- Doing a cost plus pricing helps the total cost of making the product and also an add up in the market in order to determine the pricing of the product.
--- Dynamic pricing :
Dynamic pricing is a non static pricing. Dynamic pricing is an efficient method for the market based on the supply and demand.
--- Penetration pricing :
Penetration pricing is used by the large companies which is used to capture the market share by the setting product prices at the below market level so as to gain customers.
--- Doing a research for the price skimming helps the company to set up the accurate price for the product rather than readjusting the prices of the product later on based on the demand and the supply.
