A student conducted an investigation to generate evidence to support the claim that during a chemical reaction mass is conserved. A Student combine 65 g of calcium chloride with 50 g of sodium sulfate. If the 25 g sodium chloride are produced in the reaction how much Calcium sulfate will this chemical reaction produce? PLS NO LINKS
A. 115 grams
B. 140 grams
C. 25 grams
D. 90 grams

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

1 is a answer of a question
