The pH of the substance is 3.3 which is acidic.

<h3>What is pH?</h3>

The pH of a substance or solution is referred to the degree of acidity or alkalinity of that substance. It is measured on a scale of 0 -14.

  • pH <7 are termed acidic
  • pH >7 are alkaline
  • pH =7 are termed neutral

Given  the concentration of hydrogen ions as 5. 0 × 10–4 moles per liter,we  use the formulae

ph = –log[h+]

plugging in thge value of  h+ as 5. 0 × 10–4 moles per liter we have:

pH = –log{5. 0 × 10–4 ]

pH=3.3

How does data collected in polls and studies lead us to incorrect conclusions?
pshichka [43]
<span>The data collected in any poll could be tallied inaccurately to lead others to believe incorrect conclusions. The best ways to ensure accuracy are to revisit the study questions and recount the inquiries that were provided. Other studies may have concluded prematurely and without an adequate amount of questions about the product at hand.</span>

Carmen earns $7.50 an hour pLu's tips ,as a waitress .Suppose she works 24hours in one week how much money in tips (x) must Carm
azamat

Answer:

Hours Wages = $7.5 / Hour

Since we do not know the tips , let us assume it is x

Carmen Worked 24 hours

Total amount she earned = (24*7.5) + x = 250

180 + x = 250

x = 250-180 = 70

Carmen should earn tips more than $ 70 in 24 hours in order her to receive more than $250 in that week

A piece of equipment costs $30,000, and is expected to generate $8,500 of annual cash revenues and $1,500 of annual cash expense
djverab [1.8K]

Answer:

C. 4.29 years

Explanation:

The computation of the payback period is shown below:

Payback period = Initial investment of the equipment ÷ Cash flows

where,

Initial investment = $30,000

And, the cash flows is

= $8,500 - $1,500

= $7,000

So the payback period is

= $30,000 ÷ $7,000

= 4.29 years

By dividing the initial investment by the cash flows we can get the payback period and the same is applied above.
