Answer:
The mass of NaOH that is required is 150 g
Explanation:
We calculate the weight of 1 mol of NaOH
Weight Na =23g/mol, Weight H= 1g/mol, Weight 0= 16g/mol
Weight NaOH =( 23+1 + 16) g/mol = 40 g/mol
1 dm3 (1000ml or 1 liter)---1 ,5 mol
2,5 dm3-------------------------x= (2,5dm3x 1,5mol)/ 1 dm3= 3, 75 mol
1mol NaOH----40 g
3, 75mol NaOH--x= (3, 75mol NaOHx40g)/1 mol NaOH= 150g
Answer: dependent variable
Explanation:In single variable calculus, a function is typically graphed with the horizontal axis representing the independent variable and the vertical axis representing the dependent variable. In this function, y is the dependent variable and x is the independent variable.
A collision hypothesis that claims a chemical reaction can only happen when reactants collide at the right angle and with enough kinetic energy.
<h3>What in chemistry is a reactant?</h3>
A material that's also present at the outset of such a chemical reaction is known as a reactant. Products are the substrate(s) to the side of the arrow. A component that remains after a chemical reaction is finished is known as a product.
<h3>Which side are the products and reactants?</h3>
The chemicals (what you started with) be transformed into byproducts in a chemical process (what you end with). An arrow separates the reaction mixture, which are indicated on the left side of a solution, from the products, who are depicted on the right.

Answer:
Mass of sample in mg = 15,285 mg
Explanation:
Given:
Volume of urine sample = 15 ml
Density of sample = 1.019 g/ml
FInd:
Mass of sample in mg
Computation:
Mass = density x volume
Mass of sample in mg = Volume of urine sample x Density of sample
Mass of sample in mg = 1.019 x 15
Mass of sample in mg = 15.285 gram
Mass of sample in mg = 15.285 x 1,000
Mass of sample in mg = 15,285 mg
