1 AnswerMathematics1 decade agoFinding a y coordinate and speed?
A particle starts from the origin at t=0s with a velocity of v=(8j)m/s and moves in the xy- plane with a constant acceleration of a= (4.0i+2.0j)m/s^2. At the instant the particles x coordinate is 29m what is the y coordinate and what is the speed.
1 AnswerPhysics1 decade agoHow to find maximum x coordinate?
A partical leaves the origin with an initial speed of v=(3.00i)m/s and a constant acceleration a=(-1.00i-0.50j)m/s when the particle reaches its maximum x coordinate what are its velocity and its position vector.
Note: the i's and j's represent the x and y components.

2 AnswersHome Theater1 decade agoTitration question: Given=balanced formulas, molarity of HCl //Wanted=a mass?
What is the minimum mass of sodium bicarbonate that must be sprinkled on 115.9 mL of the hydrochloric acid solution that you titrated in order to completely neutralize it?
Given:
Na2(CO3)(aq) + 2HCl(aq) ---->2NaCl(aq) + CO2(g) +H2O
.96 Molarity of HCl
if a mass is needed plug in 8g
Also, if anything is missing or more information is needed please tell what it is.
show as much work as possible thank you

1 AnswerPhysics1 decade agoFinding molarity using Lab results HELP?
Given:
Trial 1
Initial HCl(mL): .5 mL
Final HCl(mL): 12.55 mL
HCl used (mL): 12.05 mL
Initial NaOH (mL): .8 mL
Final NaOH (mL): 6.05mL
Used NaOH (mL): 5.25 mL
Molarity of HCl: ??
how do i get this n if i cant tell me what other information i need in order to find it out
Another piece of info is that we got a given Molarity for NaOH is .5 but i dont know how tht can help. Also, this is called a titration. Hope that helps.
