What happens to the total mass of the atoms involved in a chemical reaction
Daniel [21]

There won't be any change in the total mass of the atoms involved in a chemical reaction. According to the law of conservation of mass; it states that mass can neither be created nor destroyed in a chemical reaction. So, when atoms participate in a chemical reaction they might displace with other reactants but the total mass will remain the same.

4. Tests are performed to determine the Tool Life of a high speed steel single edge cutting tool. At a cutting speeds (v) of 180
podryga [215]

Answer:(a)   n=0.233

Step-by-step explanation:

Given

We Know according to Taylor tool life

VT^n=c

V=cutting speed

T=tool life

n=tool life exponent

c=constant

180\times \left ( 4.25\right )^n=110\times \left ( 35\right )^n

\frac{180}{110}=\left ( \frac{35}{4.25}\right )^n

1.636=\left ( 8.235\right )^n

taking log both side

\ln \left ( 1.636\right )=n\ln \left ( 8.235\right )

n=0.233

Determine if the expression 9y5 – 10y3 is a polynomial or not. If it is a polynomial,
Stolb23 [73]

I am going to assume that the equation was supposed to be  9y^{5}-10y^{3}

Answer:

It is a polynomial. It is a binomial and it has a degree of 5.

Step-by-step explanation:

A polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables so 9y^{5}-10y^{3} will be considered a polynomial.

A binomial is a polynomial with 2 terms.

The degree of a polynomial is the highest exponent in it which in this equation is 5.
