An 8.65-g sample of an unknown group 2a metal hydroxide is dissolved in 85.0 ml of water. an acid-base indicator is added and the resulting solution is titrated with 2.50 m hcl(aq) solution. the indicator changes color signaling that the equivalence point has been reached after 56.9 ml of the hydrochloric acid solution has been added.

Answer; The molar mass of metal hydroxide = 121.66 g/ mole The formula is Sr(OH)2 Explanation; M(OH)2 + 2 HCl = MCl2 + 2 H2O   Moles of the acid = 2.5 x 56.9 / 1000 = 0.14225   Therefore; moles of hydroxide at the eq point = 0.0711 moles …

Best answer get Brainliest. 50 points. Emerson earns money from walking dogs and answering surveys. He earns $5 a week for each dog he walks and $0.10 for each survey he answers. Last week, Emerson answered 100 surveys and earned $35. Part A: Create an equation that will determine the number of dogs he walked. (3 points) Part B: Solve this equation justifying each step with an algebraic property of equality. (6 points) Part C: How many dogs did Emerson walk last week? (1 point)

Step-by-step explanation: 5x + 10 = 35 is your equation 5x = 35 – 10    bc u brought the 10 to the other side so its symbol changes 5x = 25         now were going to bring 5 to the other side to do that we …

Trevor is pulling his younger brother in a wagon. He pulls the wagon 50 m to the corner with a force that is a parallel with the ground. He then turns the wagon around and pulls it 50 m back to the starting point with the same force at an angle of 30 degrees with respect to the ground. How does the amount of work Trevor performs going to the corner compare with the amount of work he performs coming back? A) they are the same because he uses the same amount of force B) they are the same because he travels the same distance C) he does less work coming back because the force moving the wagon is only 50cos30 D)he does more work coming back because the force moving the wagon is only 50cos60

Work has the greatest value when the force done is parallel to the direction of motion. In this case, the work done in pulling the wagon to the corner is greater than the amount of work done in pulling the wagon back to the starting point. This is because an …

My grandfather, who lost his short-term memory sometime during the first Eisenhower Administration, calls me into his study because he wants to tell me the story he’s never told anybody before again. . . . My grandfather slams the door and motions me to the chair in front of his desk. I’ll be thirteen in two weeks. “There’s something I want to tell you, son,” he says. “Something I’ve never told anybody. You think you’re ready? You think you’ve got the gumption?” “I think so.” “Think so?” “I know so, sir. I know I’ve got the gumption.” . . . “It was late,” he says. “Someone knocked on my stateroom door. I leaped up. In those days I slept in uniform—shoes, too.” My grandfather smiles. His face is so perfectly round that his smile looks like a gash in a basketball. I smile back. “Don’t smile,” he says. “Just because I’m smiling, don’t assume I couldn’t kill you right now. Know that about a man.” Source: Orner, Peter. “The Raft.” The Atlantic Online. The Atlantic Monthly Company, Apr. 2000. Web. 10 May 2011. Which point of view does the text use?

Some life forms move so slowly that their movement cannot be detected by normal observation. The best way to determine any movement is by placing a mark at some point, and observing any change in position from it. Why is this true?
