  • Question #67db3 - Socratic
    you would get about 35 8 grams of Br_2 from this reaction Let's begin with balancing our equation and figuring how much we have of everything The reaction between Calcium Bromide and Chlorine will be a single replacement reaction Therefore, we know the reaction will look a little like this: CaBr_2 + Cl_2 -> CaCl_2 + Br_2 Luckily we don't need to try and balance this equation, as it is

  • Question #73a22 - Socratic
    Let the velocity of projection of the object be u with angle of projection alpha with the horizontal direction The vertical component of the velocity of projection is usinalpha and the horizontal component is ucosalpha Now if the time of flight be T then the object will return to the ground after T sec and during this T sec its total vertical displacement h will be zero So applying the
  • Question #4fc3d - Socratic
    OK, we know that potential energy and height are related, yes? The equation is PE = m xx g xx h but we need to rearrange (a 4 term Eqn) and that’s not always easy to find height So we know PE = m xx g xx h and need h on its own on the left hand side In effect we need to “undo” the multiplication by ‘m’ and ‘g’ We do this by doing the mathematical “opposite” so we divide
  • Question #1a6e0 - Socratic
    Explanation: #color (blue) ("Defining variables")# This question is structured in such a way that it does not restrict the answer to only one particular set of values It has many solutions I choose to target the least count that satisfies all the criteria
  • Question #1f484 - Socratic
    Explanation: We'll start this integration by using substitution For #intsqrtx (e^-sqrtx)dx#, let #u=-sqrtx=-x^ (1 2)# Therefore, # (du) dx [-x^ (1 2)]=-d dx [x^ (1 2)]=- (1 2x^ (-1 2))=-1 (2sqrtx)#, so #du=-1 (2sqrtx)dx# To substitute we need something that's part of the integrand, so rearrange this to #-2sqrtxdu=dx# Now our integral looks like #intsqrtx (e^u) (-2sqrtxdu)=int-2xe^udu

  • Question #2efd1 - Socratic
    U-substitution, see explanation I will presume that you meant to write int e^(x^3)x^2dx If you did not mean this, then the solution below will not help you If so, we can solve this problem via u-substitution In u-substitution, we essentially invert the chain rule; we recognize an integrand as being an instance of f'(g(x))*g'(x), and define g(x)=u, g'(x)=du,, allowing us to instead describe
  • Question #b9560 - Socratic
    The depth of the lake = 4 9m Use the equation: P = hrhog This formula is used to find the pressure in liquids P refers to the pressure h refers to the height depth rho refers to the density of the liquid g refers to the gravitational pull of the Earth Now, make h the subject of the formula: P rhog = h Now, we assume that the density of the water is 1000kg m^3 Then, we input the values
