The correct number of significant figures : 17
<h3>Further explanation</h3>
Given
mass = 8.64 g
volume = 2 ml
Required
The density of liquid
Solution
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
Density formula:
The density :
ρ = 8.64 : 2
ρ = 4.32 g/ml
If we want to find density, then the steps should be as above
But if we ignore the density and just want to find the multiplication value to clarify the significant figure, then we must pay attention to the rule of multiplication, that is, <em>the end result of the multiplication has the least significant number of the numbers involved in multiplying.</em>
8.64 = 3 sig fig
2.0 = 2 sig fig
then the product contains 2 sig fig
8.64 x 2.0 = 17.28 rounded to 2 sig fig ⇒ 17
<span>Cell references in a formula are called electrode potentials. Electrode potentials are standard voltages for half-cell potentials. All half-cell potentials use the Standard Hydrogen Electrode (SHE) as a universal reference for redox reactions. For hydrogen, the standard electrode potential is zero for all temperatures.</span>
Answer:
A; deciduous
Explanation:
Trees that lose all of their leaves for part of the year are known as deciduous trees. Those that don't are called evergreen trees. Common deciduous trees in the Northern Hemisphere include several species of ash, aspen, beech, birch, cherry, elm, hickory, hornbeam, maple, oak, poplar and willow
The British Petroleum (bp's) effort to close the blowout preventer and install a containment dome following an explosion on the deepwater horizon drilling rig is an example of <u>regulatory policy </u>change.
The deepwater horizon drilling rig is a semi-submersible, transportable, floating, flexibly oriented drilling rig that could work in sea depths of up to 10,000 feet which is approximately 3,000 meters.
During the explosion that occurred in April 2010, British Petroleum made several efforts to contain the damages made and to prevent further outbreaks of disasters.
Part of the changes was shifting from a blowout preventer that has a specialized valve to seal, manage, and monitor oil and gas wells in order to prevent blowouts to a containment dome (a crucial component of a system meant to control an oil well's underwater blowout).
Therefore, we can conclude that the British Petroleum (bp's) effort to close the blowout preventer and install a containment dome following an explosion on the deepwater horizon drilling rig is an example of <u>regulatory policy </u>change.
