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 …

A firefighter stood on the middle rung of a ladder, spraying water on a fire. the smoke lessened, so she moved up 3 rungs. it got too hot, so she backed down 5 rungs. later, she went up 7 rungs and stayed until the fire was out. then, she climbed the remaining 4 rungs and went into the building. how many rungs does the ladder have?

How does water move underground?

Answer: Groundwater is transported through aquifers because of two main reasons: gravity and pressure. In unconfined aquifers, which we concentrate on because they are more likely to be contaminated, water always flows from high points to low points because of gravity. Explanation:

A certain skin lotion is a fine mixture of water and various oils. This lotion is cloudy and cannot be separated into oil and water by filtration. Moreover, its components do not separate when left standing. What type of mixture is it? solution suspension colloid compound NextReset

The answer is: colloid. In the presence of an emulsifying agent, a mixture of oil and water becomes a colloidal dispersion. Colloidal dispersion (colloid) is a system, in which discrete particles, droplets or bubbles of a dispersed phase (in this case oil), whose size at least in one dimension is …

In the story “To Build a Fire,” what information did the man ignore? Even though the creeks freeze solid, liquid water exists near springs. Always make camp and build a fire while there is still daylight. Always take along survival gear and wear protective clothing. No one must travel alone in the Klondike after fifty degrees below zero.

Answered by answersmine AT 22/10/2019 – 03:28 AM No one must travel alone in the Klondike after fifty degrees below zero. I would say this is the main lesson to learn about this Jack London story which shows that nature can be cruel and unforgiving and at 50 degrees below …

Think about an igneous rock at the top of a mountain. If this rock went through the whole rock cycle, number the steps that would follow. 1. Step 1 Regolith is dumped into some type of reservoir, usually water, by deposition. 2. Step 2 Metamorphic rock begins to melt back into magma. 3. Step 3 Regolith is transported or eroded by rain or wind. 4. Step 4 Rock is broken down into regolith by weathering. 5. Step 5 Layers deposited begin to compact and cement together to form sedimentary rock. 6. Step 6 Sedimentary rock is buried deeper into the earth’s crust. The intense heat and pressure begins metamorphism and the rock turns into metamorphic rock. 7. Step 7 Magma is resurfaced from volcanic activity, cools, and becomes igneous rock.

Answer: The correct sequence according to the question is steps- 4→1→3→5→6→2→7. Explanation: The given steps show that how the rocks are recycled from one form to another form due to certain factors like weathering over geological time scale which was explained by James Hutton and he termed this concept as …
