Thank you to whoever is able to help! Any help is appreciated! :)

(this is all the given information)

1. In the laboratory you dilute 5.39 mL of a concentrated 6.00 M hydrochloric acid solution to a total volume of 50.0 mL. What is the concentration of the dilute solution? _____________ M

2. In the laboratory you dilute 4.09 mL of a concentrated 6.00 M perchloric acid solution to a total volume of 100 mL. What is the concentration of the dilute solution? _____________ M

3. In the laboratory a student combines 30.8 mL of a 0.322 M chromium(II) bromide solution with 14.9 mL of a 0.474 M chromium(II) acetate solution.

What is the final concentration of chromium(II) cation ? ____________ M

(a) A student prepares a solution by obtaining 168 mL from 0.100 M of NaOH and diluting it to a total volume of 634 mL. What is the concentration of the solution prepared by the student? (b) How many milliliters of 9.500 M perchloric acid solution should be used to prepare 0.2890 L of 0.7000 M of perchloric acid? A student adds 28.7 mL of water to 89.9 mL of a 5.10 M glucose solution. (i) Will this solution be concentrated or dilute? -concentrated -dilute (ii) What is the concentration of the solution?

I cannot understand whyleading 00 in number 0.00620 are notsignificant digits?
Please explain?

Draw a SMD for the transverse axis of the S-IC using symbolic values (no numbers). The diagram should reflect: 1. A constant, even transverse pressure the vehicle experiences due to wind at the pad (note that this must include the wind pressure experienced by the upper stages, collectively referred to as 𝑃𝑊). 2. The fixed base of the vehicle on the pad. 3. A fueling arm located at 𝑙/2 from the base of the rocket that exerts a load 𝑃𝑓 in a direction counter to the wind. 𝑃𝑓 is not large enough to counteract all the shear experienced by the stage at station 𝑙/2. 07 Hint: for this problem, continue drawing the SMD along the X axis, with the fixed base at the bottom of the rocket.

The Early Romantic period continued to develop a more dynamic difference between soft and loud parts in a composition, called

The PMIS system is one of the leanest systems around, but it is far from agile in terms of responding to new requirements’.

Critically explore and evaluate this statement in relation to lean and agile methodologies. You should include academic literature and examples within your answers.
