What is the result of a 2 to 1 lecithin and sphingomyelin ratio?
Wiki User
∙ 16y ago

How do you determine the ratio of water to cement?
Concrete hardens as a result of the chemical reaction between cement and water so that for every 4 lbs of cement 1 lb of water is needed. The ratio is therefore 1:4 or 20%. This mix will be too dry so more water is needed than is technically necessary, the ratio should therefore be 35% to 40% and using a plasticizer
Can a petrol engine run on lean air-fuel ratio such as 30 by 1 while a diesel engine can?
No, the perfect fuel/air ratio is 14.6 to 1. A ratio of 13 to 1 is a safe ratio for most non turbo gas engines. Turbo engines can run a 12 to 1 ratio. Chrysler's lean burn system of the 70's and 80's used a ratio of around 18 to 1 and it was horrible. No gasoline engine can run at 30 to 1.
What is cement sand ratio in plastering?
The type of sand is also important. The right ratio for a mixture of cement and sand is 1:5 to 1:6
What is fuel air ratio?
Air to fuel ratio is the ratio between the weight of air to the weight of fuel, for example: 14.7 pounds of air to 1 pound of fuel would be a air:fuel ratio of 14.7:1 This particular example is called the stoichiometric ratio for gasoline...it's ideal ratio in order to efficiently use all the fuel. This ratio varies for different fuels....for example, ethanol fuels have a stoichiometric air:fuel ratio of 13.85:1. In actuality, a gasoline car gets it's best fuel mileage when the fuel is reduced slightly and produces it's best power when the ratio is a little heavier on the fuel side.
What is the sand to cement mix ratio for Type N masonry cement?
1:5 (cement:sand) is the best ratio

Does sunflower lecithin contain phosphatidylserine?

What does the oxidation number of an element tell you?
The oxidation number tells you the "combining power" of that element. For example, if Cu has a 1+ oxidation number then it will combine with Cl in a 1:1 ratio, and result in CuCl. If Cu has an oxidation number of 2+, then it will combine with Cl in a 1:2 ratio, and result in CuCl2.

Which is the recursive formula for the nth term in a geometric sequence?
You need to know two numbers to completely describe the geometric sequence: the starting number, and the ratio between each number and the previous one. When you use recursion, you always need a "base case", otherwise, the recursion will repeat without end. In words, if "n" is 1, the result is the starting term. Otherwise, it is the ratio times the "n-1"th term. The following version is appropriate for a programming language (written here in pseudocode, i.e., not for a specific language): function geometric(starting_number, ratio, term) if term = 1: result = starting_number else: result = ratio * geometric(starting_number, ratio, term - 1)
What is the ratio of atoms found in all carbohydrates?
Carbohydrates are generally made of monosaccharides (i.e. simple sugars), like glucose (C6H12O6). As a result, the ratio of elements for carbohydrate sugars (C:H:O) would be 1:2:1.

How do you solve for debt to equity ratio with an equity multiplier of 2.47?
Equity Multiplier = 2.4 Therefore Equity Ratio = 1/EM Equity Ratio = 1/2.4 = 0.42 MEMORIZE this formula: Debt Ratio + Equity Ratio = 1 Therefor Debt Ratio = 1 - Equity Ratio = 1 - 0.42 = 0.58 or 58%
What is the ratio of the angles of an equilateral triangle?
They are all the same so the ratio is 1:1:1.They are all the same so the ratio is 1:1:1.They are all the same so the ratio is 1:1:1.They are all the same so the ratio is 1:1:1.
Which punnett square shows the result of a cross between two heterozygous parents?
