For an object to sink in something, it's density has to be higher than the object it is in, so if it sinks in water the number has be higher than 1
And to float, and objects density has to be lower than that of the substance it is put in, so it has to be lower than 1.26
So between 1 and 1.26
Answer:
Here’s what I get.
Explanation:
- The atomic number is the number of protons in the nucleus of an atom.
- The number of protons determines the number of electrons.
- The number of electrons determines the chemical properties of the element,
Thus, the atomic number determines the identity of the element.
The atomic mass does not affect the chemical properties, so different isotopes of an element behave alike.
Answer:
Explained
Explanation:
The bond angle between the Si-O-Si is 145° .But this can also vary between 100° and 170°, It is because of which the changes in properties is happening. Bond angles can affect the hybridization, lone pair repulsion and electronegativity.
Thus , Space shuttle tiles, sandstone, and the glass in quartz have different properties and are used according to their property.
Molar solubility is number of moles of the solute that can be dissolved per liter of solution before the solution becomes saturated.
The molar solubility of lead(ii) chloride with ksp value of 2.4 × 10e4 can be solve as:
Ksp = s2 = 2.4 × 10e4
s2 = 2.4 × 10e4
s = √(2.4 × 10e4)
s = 154.9 mol/L
The answer to this question is 6.25ml
To answer this question, you need to calculate the azithromycin drug doses for this patient. The calculation would be: 25kg * 10mg/kg/d= 250mg/d
Then multiply the doses with the available drug. It would be:
250 mg/d / (200mg/5ml)= 6.25ml/d
