his is LINEAR ALGEBRA & MATRICIES Ill give thumbs up for
steps on how to do the problem and solutions.
your responses. (a) The dimension of Maa l (b) Does S span the vector space Maxa (c) Is S a basis for M2zxa? Justify your answer.
PLEASE
DO 1,3 FOR A THUMBS UP, if NOT than ill thumbs down. PLEASE be
oraganize and detailed on the work!!
1. (15 points) Determine the masses of NazCO) and NaHCO, that would be required to prepare 500.0 mL of a pH 9.80 buffer with a total concentration of 0.120 M (here total means the sum of the carbonate and hydrogen carbonate concentrations). For H.CO, PK -6.13 and pk 9.91. 3. (15 points) Consider the reaction HIO, (aq) → H(aq)...
please answer fast ill give thumbs up!! show work!! do fast please

You are a manager at Northern Fibre, which is considering
expanding its operations in synthetic fibre manufacturing. Your
boss comes into your office, drops a consultant's report on your
desk, and complains, "We owe these consultants $1.9 million for
this report, and I am not sure their analysis makes sense. Before
we spend the $23 million on new equipment needed for this project,
look it over and give...
Will leave a thumbs up!! A) The boiling point of water is 100.0°C at 1 atmosphere. How many grams of potassium nitrate (101.1 g/mol), must be dissolved in 268.0 grams of water to raise the boiling point by 0.500°C? Refer to the table for the necessary boiling or freezing point constant.

Please provide a clean,
legible solution with space between steps, and I'll leave a thumbs
up. Thanks:)
Use linkage transformation on the linkage below to make it have 1 DOF --
both questions plz. ill make sure to give you a thumbs
up
consider Question 10 1 pts If the concentration of a reactant at 34 seconds is D.056 M and the rate constant is 0.034s 1, what was the initial concentration ot the reaction D Question 11 1 pts Find the half-tfe of a zero order reaction where the initial concentration is 3.0 M and the rat constant 0.027 M
